The `receive()` function accepts it, but only the admin can rescue it via `rescueETH`. +- **Exploit Scenario:** A session key holder calls `executeHooks{value: 1 ether}(...)`. The strategy partially uses the ETH and refunds 0.5 ETH to `msg.sender` (SessionKeyManager). The 0.5 ETH is now stuck until admin calls `rescueETH`. +- **Secure Pattern:** This is an accepted trade-off given the `rescueETH` function exists. Consider documenting this behavior and ensuring `rescueETH` is called periodically, or forwarding refunds back to `msg.sender` if the strategy supports a recipient parameter. +- **Reference:** EVM Security Research (ETH forwarding patterns) + +### [P2-4] Session Key Resurrection on Manager Reinstatement +- **File:** `src/SuperVault/SessionKeyManager.sol:193-200` +- **SWC:** N/A +- **Category:** Logic +- **Description:** If a primary manager is replaced and then reinstated (e.g., `A → B → A`), all session keys originally granted by `A` that haven't expired become valid again without `A` re-granting them. The `grantedByManager` check passes again. +- **Exploit Scenario:** Manager A grants a session key with 30-day expiry. Manager is changed to B (invalidating the key). Manager is changed back to A. The old session key is now valid again for the remaining duration — even if A didn't intend to re-authorize it. +- **Secure Pattern:** Add an epoch/nonce counter per strategy that increments on every manager change, and store the epoch at grant time. This would require aggregator changes. Alternatively, document as a known behavior and recommend explicit revocation before manager reinstatement. +- **Reference:** EVM Security Research (stale authorization patterns) + +### [P2-5] TOCTOU Race on Session Key Validation During Manager Change +- **File:** `src/SuperVault/SessionKeyManager.sol:193-200` +- **SWC:** N/A +- **Category:** Logic +- **Description:** A session key holder's transaction can be front-run by a `executeChangePrimaryManager` call, causing the session key to become invalid mid-flight. This is a time-of-check-to-time-of-use race condition on the manager state. However, the impact is limited — the session key holder's tx simply reverts with `PRIMARY_MANAGER_CHANGED`. +- **Secure Pattern:** This is an inherent trade-off of the design (checking live state). The behavior is correct — invalid keys should revert. No fix needed, but document the race condition. +- **Reference:** EVM Security Research (TOCTOU patterns) + +--- + +## P3 Findings (Low - Consider Fixing) + +### [P3-1] `memory` Instead of `calldata` for fulfillCancelRedeemRequests Controllers +- **File:** `src/SuperVault/SessionKeyManager.sol:106` +- **SWC:** N/A +- **Category:** Gas +- **Description:** The `controllers` parameter uses `memory` instead of `calldata`, causing unnecessary memory copy. This matches the upstream interface signature so it's constrained by `ISuperVaultStrategy`. +- **Current Code:** `function fulfillCancelRedeemRequests(address strategy, address[] memory controllers)` +- **Note:** Cannot change without also changing the interface. Low priority. + +### [P3-2] Missing Zero-Balance Check in rescueETH +- **File:** `src/SuperVault/SessionKeyManager.sol:170-176` +- **Category:** Gas +- **Description:** `rescueETH` will execute a zero-value ETH transfer if the contract has no balance, wasting gas. Consider adding `if (balance == 0) revert NO_ETH_TO_RESCUE()`. + +### [P3-3] Missing Empty Array Check in Batch Functions +- **File:** `src/SuperVault/SessionKeyManager.sol:62-76, 85-93` +- **Category:** Logic +- **Description:** `grantSessionKeysBatch` and `revokeSessionKeysBatch` allow empty arrays, executing a no-op loop. Consider adding `if (len == 0) revert EMPTY_ARRAY()`. + +### [P3-4] No Strategy Address Validation +- **File:** `src/SuperVault/SessionKeyManager.sol:56-59, 100-103` +- **Category:** Logic +- **Description:** No check that `strategy != address(0)` on grant or forwarding calls. However, `_validatePrimaryManager` and `_validateSessionKey` will revert for `address(0)` since `isMainManager` would return false, providing implicit protection. + +### [P3-5] Block Timestamp Manipulation +- **File:** `src/SuperVault/SessionKeyManager.sol:148, 196, 206` +- **Category:** Logic +- **Description:** Expiry checks use `block.timestamp` which validators can manipulate by ~15 seconds. Given that session keys have hours/days-long expiries, this is negligible. + +### [P3-6] Unbounded Batch Operations +- **File:** `src/SuperVault/SessionKeyManager.sol:62-76, 85-93` +- **Category:** DoS +- **Description:** No upper bound on batch array length. Extremely large arrays could hit block gas limits. In practice, callers are primary managers who won't DOS themselves. + +### [P3-7] msg.value Forwarding in Batched Context +- **File:** `src/SuperVault/SessionKeyManager.sol:100-103` +- **Category:** Logic +- **Description:** If `executeHooks` were called multiple times in a multicall pattern, `msg.value` would be reused. However, SessionKeyManager doesn't have a multicall function, so this is not exploitable. + +### [P3-8] Dynamic Registry Resolution Trust Dependency +- **File:** `src/SuperVault/SessionKeyManager.sol:220-222` +- **Category:** Logic +- **Description:** `_getAggregator()` resolves the aggregator dynamically via SuperGovernor. If SuperGovernor is compromised, the aggregator address could be changed to a malicious contract. This is an accepted trust assumption — SuperGovernor is a trusted governance contract. + +### [P3-9] AccessControl Without DefaultAdminRules +- **File:** `src/SuperVault/SessionKeyManager.sol:14` +- **Category:** Access Control +- **Description:** Uses `AccessControl` instead of `AccessControlDefaultAdminRules` which adds a 2-step admin transfer with timelock. Given this is a single-role contract (only DEFAULT_ADMIN_ROLE for rescueETH), the additional complexity is likely unnecessary. + +### [P3-10] SessionKeyData Struct Defined in Implementation, Not Interface +- **File:** `src/SuperVault/SessionKeyManager.sol:19-22` +- **Category:** Code Quality +- **Description:** The `SessionKeyData` struct is defined in the implementation contract rather than the interface. Since it's only used internally (private mapping), this is acceptable. + +### [P3-11] Cross-Strategy Reentrancy via executeHooks +- **File:** `src/SuperVault/SessionKeyManager.sol:100-103` +- **Category:** Reentrancy +- **Description:** A malicious hook could re-enter `executeHooks` for a different strategy during execution. However, the session key validation is read-only (view) and no state is modified before the external call, so reentrancy cannot manipulate SessionKeyManager state. The strategy itself has its own reentrancy guards. + +--- + +## Attack Surface Summary + +### External Entry Points +| Function | Access | Modifies State | +|----------|--------|---------------| +| `grantSessionKey` | Primary manager | Yes (storage) | +| `grantSessionKeysBatch` | Primary manager | Yes (storage) | +| `revokeSessionKey` | Primary manager | Yes (storage) | +| `revokeSessionKeysBatch` | Primary manager | Yes (storage) | +| `executeHooks` | Session key holder | No (forwards) | +| `fulfillCancelRedeemRequests` | Session key holder | No (forwards) | +| `fulfillRedeemRequests` | Session key holder | No (forwards) | +| `skimPerformanceFee` | Session key holder | No (forwards) | +| `pauseStrategy` | Session key holder | No (forwards) | +| `unpauseStrategy` | Session key holder | No (forwards) | +| `rescueETH` | DEFAULT_ADMIN_ROLE | Yes (ETH transfer) | +| `receive` | Anyone | Yes (ETH receive) | + +### Value Transfer Points +- `executeHooks`: Forwards `msg.value` to strategy +- `rescueETH`: Sends contract ETH balance to recipient +- `receive()`: Accepts ETH (for refunds from strategies) + +### Cross-Contract Interactions +- `ISuperGovernor.getAddress()` — resolves aggregator address +- `ISuperGovernor.SUPER_VAULT_AGGREGATOR()` — gets aggregator key +- `ISuperVaultAggregator.isMainManager()` — validates primary manager +- `ISuperVaultAggregator.pauseStrategy()` / `unpauseStrategy()` — forwards pause/unpause +- `ISuperVaultStrategy.executeHooks()` — forwards hook execution +- `ISuperVaultStrategy.fulfillCancelRedeemRequests()` — forwards cancel requests +- `ISuperVaultStrategy.fulfillRedeemRequests()` — forwards redeem fulfillment +- `ISuperVaultStrategy.skimPerformanceFee()` — forwards fee skimming + +### Trust Assumptions +- SuperGovernor is trusted and not compromised +- Aggregator resolved via SuperGovernor returns correct address +- Primary managers are trusted actors who grant keys responsibly +- Strategy contracts are trusted (deployed by the protocol) + +## Coding Standards Findings +- Custom errors used consistently (except `require(success)` in rescueETH — P2-1) +- Events emitted for all state changes +- NatSpec documentation complete via `@inheritdoc` +- Import organization follows project conventions +- Naming conventions followed (SCREAMING_SNAKE for errors, camelCase for functions) +- Checks-Effects-Interactions pattern followed (validation before external calls) + +## Security Knowledge Sources +- **vulnerabilities.md sections referenced:** 1 (Reentrancy), 2 (Access Control), 3 (Arithmetic), 8 (Unchecked Returns), 9 (Encoding), 13 (Gas), 15 (Code Quality), 36 (Pre-PR Checklist) +- **evmresearch.io patterns checked:** Delegation patterns, session key implementations, ETH forwarding, TOCTOU in authorization +- **Coding rules validated:** Custom errors, events, NatSpec, naming, imports, CEI pattern +- **Historical exploits cross-referenced:** Access control bypasses, stale authorization resurrection, ETH trapping in proxy/forwarder contracts diff --git a/specs/security-reports/2026-03-18-supervault-manager-v2.md b/specs/security-reports/2026-03-18-supervault-manager-v2.md new file mode 100644 index 000000000..70adaa83c --- /dev/null +++ b/specs/security-reports/2026-03-18-supervault-manager-v2.md @@ -0,0 +1,465 @@ +# Security Analysis Report (v2 — Post-Fix Re-Analysis) + +## Metadata +- **Target:** `src/SuperVault/SuperVaultManager.sol`, `src/interfaces/SuperVault/ISuperVaultManager.sol` +- **Mode:** threat-model +- **Date:** 2026-03-18 +- **Contract Types Detected:** Session key delegation / forwarding proxy for vault operations +- **Files Analyzed:** 2 +- **Previous Report:** `specs/security-reports/2026-03-18-supervault-manager.md` + +## Summary +| Severity | Count | Blocks Merge | +|----------|-------|-------------| +| P0 Critical | 0 | Yes | +| P1 High | 0 | Yes | +| P2 Medium | 3 | No | +| P3 Low | 7 | No | + +## Verdict +**PASS** — No P0 or P1 findings.

Session Key Revival After Manager Rotation (Documented Design Decision) + +- **File:** `SuperVaultManager.sol:237-240` +- **SWC:** N/A +- **Category:** Logic +- **Description:** When a primary manager changes (A → B), session keys granted by A are logically invalidated because `isMainManager(A, strategy)` returns false. However, the key data persists in storage. If governance later re-instates A (A → B → A), all previously granted session keys by A silently reactivate — including ones the manager intended to revoke before the transition. +- **Status:** Documented with `@dev WARNING` comment. The re-instated manager is responsible for revoking stale keys. A per-strategy generation counter would provide stronger guarantees but adds storage and complexity. +- **Sources:** Vulnerability Scanner, Best Practices Agent, EVM Security Researcher + +### 2. Cross-Function Reentrancy on Unguarded Forwarding Functions + +- **File:** `SuperVaultManager.sol:143-176` +- **SWC:** SWC-107 +- **Category:** Reentrancy +- **Description:** Only `executeHooks` has `nonReentrant`. The other forwarding functions (`fulfillCancelRedeemRequests`, `fulfillRedeemRequests`, `skimPerformanceFee`, `pauseStrategy`, `unpauseStrategy`) make external calls without reentrancy protection. If a malicious strategy callback re-enters one of these functions targeting a different strategy, it could execute unintended operations. +- **Mitigating Factors:** + - These functions do not handle ETH or modify SuperVaultManager state + - Each strategy has its own `nonReentrant` guard + - Session key validation includes an external call to the aggregator, adding cost/complexity to re-entry + - Exploitable only if a malicious session key holder controls a strategy contract (they already have privileged access) +- **Risk Assessment:** Low practical risk. The attack requires a compromised session key AND a malicious strategy, at which point the attacker already has direct access. Adding `nonReentrant` to all forwarding functions is defense-in-depth but not strictly necessary. +- **Source:** EVM Security Researcher + +### 3. Forced ETH Injection via `selfdestruct` During Strategy Call + +- **File:** `SuperVaultManager.sol:127-129` +- **SWC:** N/A +- **Category:** ETH Handling +- **Description:** The balance-delta pattern (`address(this).balance - balanceBefore`) assumes the only ETH inflow during the strategy call is from the strategy itself. If a third party uses `selfdestruct` to force ETH into the manager during the strategy call, the inflated balance delta causes an over-refund to the caller. +- **Mitigating Factors:** + - `selfdestruct` is deprecated (EIP-6049) and will be removed in a future hard fork + - Requires the attacker to destroy a contract containing ETH, timed precisely during the strategy call + - The attacker loses the ETH they self-destruct — the "over-refund" comes from the attacker's own funds + - Net effect: attacker donates ETH to the session key caller (no profit for attacker) +- **Risk Assessment:** Negligible practical risk. No profitable attack vector exists. +- **Source:** EVM Security Researcher + +--- + +## P3 Findings (Low) + +### 4. Forwarding All Remaining Gas to ETH Refund Recipient + +- **File:** `SuperVaultManager.sol:134-135` +- **Category:** Gas +- **Description:** The assembly `call(gas(), ...)` forwards all remaining gas to the refund recipient. A malicious session key contract could use this gas for expensive operations in its `receive()`. However, this is self-griefing only — the session key holder pays for their own gas. +- **Source:** Vulnerability Scanner + +### 5. Uncached Aggregator in Single-Item Functions + +- **File:** `SuperVaultManager.sol:167-176` +- **Category:** Gas +- **Description:** `pauseStrategy` and `unpauseStrategy` call both `_validateSessionKey` (which calls `_getAggregator()`) and then `_getAggregator()` again directly. This results in 2 external calls to SuperGovernor per invocation. Could be optimized by caching, but the gas savings are minimal for single-item operations. +- **Source:** Vulnerability Scanner + +### 6. No Upper Bound on Session Key Expiry + +- **File:** `SuperVaultManager.sol:241-249` +- **Category:** Logic +- **Description:** A primary manager can set `expiry = type(uint256).max`, creating a session key that never expires. The `grantedByManager` check provides a safety net (key is invalidated if the manager changes), but a long expiry is still risky if the manager remains unchanged. Consider adding a `MAX_EXPIRY_DURATION` constant. +- **Source:** Vulnerability Scanner + +### 7. Interface Missing Public Getter Declarations + +- **File:** `ISuperVaultManager.sol` +- **Category:** Best Practices +- **Description:** The interface does not declare `SUPER_GOVERNOR()` or `MAX_BATCH_SIZE()` public getters, even though these are publicly accessible on the implementation. Adding these to the interface improves discoverability and allows typed access from other contracts. +- **Source:** Best Practices Agent + +### 8. `receive()` Placement in Source File + +- **File:** `SuperVaultManager.sol:203` +- **Category:** Style +- **Description:** `receive()` is placed between the VIEW FUNCTIONS section and INTERNAL FUNCTIONS section. Solidity style guides typically place `receive()`/`fallback()` near the top of the contract or in a dedicated section. +- **Source:** Best Practices Agent + +### 9. Missing NatSpec on Internal Functions + +- **File:** `SuperVaultManager.sol:212-261` +- **Category:** Documentation +- **Description:** Internal functions have `@dev` comments but lack `@param` and `@return` tags. While internal functions don't appear in the ABI, consistent NatSpec aids code review and maintenance. +- **Source:** Best Practices Agent + +### 10. No ETH Sweep / Recovery Mechanism + +- **File:** `SuperVaultManager.sol:203` +- **Category:** ETH Handling +- **Description:** ETH sent directly to the contract (outside `executeHooks`) via `receive()` is permanently stuck. The balance-delta pattern correctly prevents this ETH from being claimed by `executeHooks` callers, but there is no admin function to recover it. Consider adding a `sweepETH()` function restricted to `DEFAULT_ADMIN_ROLE`. +- **Source:** EVM Security Researcher + +--- + +## Attack Surface Summary + +**External Entry Points:** +| Function | Auth | ETH | External Calls | Reentrancy Guard | +|----------|------|-----|----------------|-----------------| +| `grantSessionKey` | Primary manager | No | `_getAggregator().isMainManager()` | No (view only) | +| `grantSessionKeysBatch` | Primary manager | No | `_getAggregator().isMainManager()` x N | No (view only) | +| `revokeSessionKey` | Primary manager | No | `_getAggregator().isMainManager()` | No (storage delete) | +| `revokeSessionKeysBatch` | Primary manager | No | `_getAggregator().isMainManager()` x N | No (storage delete) | +| `executeHooks` | Session key | Yes | `strategy.executeHooks()` + ETH refund | **Yes** | +| `fulfillCancelRedeemRequests` | Session key | No | `strategy.fulfillCancelRedeemRequests()` | No | +| `fulfillRedeemRequests` | Session key | No | `strategy.fulfillRedeemRequests()` | No | +| `skimPerformanceFee` | Session key | No | `strategy.skimPerformanceFee()` | No | +| `pauseStrategy` | Session key | No | `aggregator.pauseStrategy()` | No | +| `unpauseStrategy` | Session key | No | `aggregator.unpauseStrategy()` | No | +| `receive` | Anyone | Yes | None | No | + +**Architectural Trust Assumptions (System-Wide, Not SuperVaultManager-Specific):** +- SuperGovernor integrity (registry resolution) +- Aggregator `isMainManager()` correctness +- Strategy-level parameter validation for all forwarded calls +- Session key credential security (operational concern) + +**Design Strengths:** +- Session keys are per-strategy scoped (cross-strategy isolation) +- Primary manager changes automatically invalidate all session keys +- Two-tier validation (expiry + manager liveness) prevents stale authorizations +- Balance-delta ETH tracking prevents stray ETH theft +- Assembly refund prevents return bomb DoS +- ReentrancyGuard on the only ETH-handling function +- Batch size limits prevent gas DoS +- No upgradability (immutable deployment) + +--- + +## Improvements Since v1 Report + +| v1 Finding | Severity | Status | Implementation | +|-----------|----------|--------|----------------| +| ETH refund sends entire balance | P2 | **Fixed** | Balance-delta tracking | +| Missing reentrancy guard | P2 | **Fixed** | `nonReentrant` on `executeHooks` | +| Return bomb attack | P2 | **Fixed** | Assembly `call()` | +| Stale key reactivation | P2 | **Documented** | `@dev WARNING` comment | +| Open `receive()` accumulation | P3 | **Fixed** | Balance-delta prevents theft | +| Overwrite without check | P3 | **Accepted** | Intentional re-grant behavior | +| Misleading revoke events | P3 | **Fixed** | No-op for non-existent keys | +| Missing ETH refund event | P3 | **Fixed** | `ETHRefunded` event | +| `memory` instead of `calldata` | P3 | **Fixed** | Changed to `calldata` | +| Redundant aggregator calls | P3 | **Fixed** | Cached in batch loops | +| Unbounded batch size | P3 | **Fixed** | `MAX_BATCH_SIZE = 50` | +| Unused `DEFAULT_ADMIN_ROLE` | P3 | **Documented** | `@dev` comment on constructor | + +--- + +## Recommended Actions (Prioritized) + +1. **Consider `nonReentrant` on all forwarding functions** — Defense in depth (Finding 2).

ETH Refund Sends Entire Contract Balance, Not Caller's Overpayment + +- **File:** `SuperVaultManager.sol:107` +- **SWC:** SWC-107 +- **Category:** Reentrancy / ETH Handling +- **Description:** `executeHooks` refunds `address(this).balance` after the strategy call. Since `receive()` accepts ETH from anyone, stray ETH in the contract (accidental sends, self-destructs) would be claimed by the next `executeHooks` caller. Combined with the lack of a reentrancy guard, a malicious session key contract could re-enter during the refund callback. +- **Exploit Scenario:** Someone accidentally sends 10 ETH to the manager. Any session key holder calls `executeHooks` with `msg.value = 0` and claims all 10 ETH. With reentrancy, they could amplify this across strategies. +- **Vulnerable Code:** + ```solidity + uint256 remaining = address(this).balance; + if (remaining > 0) { + (bool success,) = msg.sender.call{ value: remaining }(""); + ``` +- **Secure Pattern:** + ```solidity + // Track only the caller's overpayment + uint256 balanceBefore = address(this).balance - msg.value; + ISuperVaultStrategy(strategy).executeHooks{ value: msg.value }(args); + uint256 refund = address(this).balance - balanceBefore; + if (refund > 0) { + (bool success,) = msg.sender.call{ value: refund }(""); + if (!success) revert ETH_REFUND_FAILED(); + } + ``` + +### 2. Missing Reentrancy Guard on `executeHooks` + +- **File:** `SuperVaultManager.sol:102` +- **SWC:** SWC-107 +- **Category:** Reentrancy +- **Description:** `executeHooks` makes an external call to the strategy, then sends ETH to `msg.sender`. No `nonReentrant` modifier protects against callback re-entry. While the strategy's own `nonReentrant` prevents re-entering the same strategy, a malicious session key could re-enter targeting a different strategy. +- **Secure Pattern:** Add `ReentrancyGuard` from OpenZeppelin and apply `nonReentrant` to `executeHooks`. + +### 3. Return Bomb Attack on ETH Refund + +- **File:** `SuperVaultManager.sol:109` +- **SWC:** N/A +- **Category:** DoS / Gas +- **Description:** The low-level `.call{value: remaining}("")` to `msg.sender` copies all returndata into memory. A malicious session key contract could return enormous data in its `receive()`, causing memory expansion to consume all gas. The strategy call would have already succeeded, but the ETH refund would fail, leaving ETH stuck in the contract. +- **Secure Pattern:** Use assembly to avoid returndata copy: + ```solidity + assembly { + let s := call(gas(), caller(), remaining, 0, 0, 0, 0) + if iszero(s) { revert(0, 0) } + } + ``` + +### 4. Stale Session Keys Reactivate if Manager is Re-instated + +- **File:** `SuperVaultManager.sol:193-200` +- **SWC:** N/A +- **Category:** Logic +- **Description:** When a primary manager changes (A -> B), session keys granted by A are logically invalidated because `isMainManager(A, strategy)` returns false. However, the key data remains in storage. If governance later re-instates A as primary manager (A -> B -> A), all previously granted session keys by A become valid again, even ones that were intended to be invalidated by the manager change. +- **Secure Pattern:** Document this behavior and require the re-instated manager to proactively revoke stale keys. Alternatively, add a per-strategy generation counter that increments on each manager change. + +--- + +## P3 Findings (Low) + +### 5. Open `receive()` Allows Unrecoverable ETH Accumulation + +- **File:** `SuperVaultManager.sol:175` +- **Category:** ETH Handling +- **Description:** `receive()` accepts ETH from anyone. ETH sent outside `executeHooks` context has no recovery mechanism. Combined with Finding 1, this ETH is claimable by the next `executeHooks` caller. + +### 6. Session Key Overwrite Without Existence Check + +- **File:** `SuperVaultManager.sol:203-211` +- **Category:** Logic +- **Description:** `_grantSessionKey` silently overwrites existing keys. No maximum expiry cap exists -- a manager could set `expiry = type(uint256).max`. The `grantedByManager` invalidation provides a safety net, but a long expiry is still risky if the manager stays unchanged. + +### 7. Revoking Non-existent Keys Emits Misleading Events + +- **File:** `SuperVaultManager.sol:214-217` +- **Category:** Logic +- **Description:** `_revokeSessionKey` emits `SessionKeyRevoked` even for keys that were never granted, confusing off-chain monitoring. + +### 8. Missing ETH Refund Event + +- **File:** `SuperVaultManager.sol:107-111` +- **Category:** Best Practices +- **Description:** ETH refund transfer emits no event, making it untrackable off-chain. + +### 9. `memory` Instead of `calldata` for `controllers` Parameter + +- **File:** `SuperVaultManager.sol:115`, `ISuperVaultManager.sol:86` +- **Category:** Gas +- **Description:** `fulfillCancelRedeemRequests` uses `memory` for `controllers`. Using `calldata` saves gas on ABI decode. + +### 10. Redundant `_getAggregator()` Calls in Batch Loops + +- **File:** `SuperVaultManager.sol:73-76, 91-94` +- **Category:** Gas +- **Description:** `_validatePrimaryManager` calls `_getAggregator()` on every iteration (2 external calls per loop). Caching the aggregator before the loop saves `2*(n-1)` external calls. + +### 11. Unbounded Batch Array Size + +- **File:** `SuperVaultManager.sol:62-77, 86-95` +- **SWC:** SWC-128 +- **Category:** DoS / Gas +- **Description:** No upper bound on batch size. Large arrays with external calls per iteration could exceed block gas limit. + +### 12. `DEFAULT_ADMIN_ROLE` is Unused Post-Construction + +- **File:** `SuperVaultManager.sol:48` +- **Category:** Access Control +- **Description:** `DEFAULT_ADMIN_ROLE` is granted but never checked in any function.
