Summary

This PR extends Claude Code support to work with alternative AI providers through environment variable overrides, specifically supporting Z.ai, Qwen (Alibaba Cloud), and DeepSeek.

Changes

Backend Enhancements

  • Configuration Reading: Added support for reading Claude Code configuration from multiple locations:

    • ~/.claude/settings.json (global user settings)
    • ~/.claude/settings.local.json (local user settings)
    • ./.claude/settings.json (project-specific settings)
    • ./.claude/settings.local.json (project-specific local settings)
    • ~/.claude.json (main global config)
  • Provider Detection: Automatically detects alternative providers based on ANTHROPIC_BASE_URL:

    • Z.ai: https://api.z.ai/v1
    • Qwen/Alibaba Cloud: https://dashscope.aliyuncs.com/api/v1
    • DeepSeek: https://api.deepseek.com/v1
  • Dynamic Model Selection: Each provider has its own set of supported models that are dynamically loaded

  • Environment Variable Passing: Passes environment variables from Claude Code config to the subprocess

Frontend Updates

  • Updated ApiOptions.tsx to display alternative provider models dynamically
  • Models are fetched from the backend when an alternative provider is detected

Testing

  • Added comprehensive test suite for the new functionality
  • Updated existing tests to handle async initialization
  • All tests passing ✅

How to Test

  1. Configure Claude Code to use an alternative provider:

    • Create ~/.claude/settings.json with:
    {
      "env": {
        "ANTHROPIC_BASE_URL": "https://api.z.ai/v1",
        "ANTHROPIC_MODEL": "glm-4.5",
        "ANTHROPIC_API_KEY": "your-api-key"
      }
    }
  2. Open Roo Code and select Claude Code as the provider

  3. The model dropdown should now show the alternative provider's models

  4. Test that code generation works with the alternative provider

To fix this, we should:

  • Properly parse the given baseUrl as a URL object.
  • Extract the host (and optionally the hostname) using standard parsing, for example with new URL(baseUrl).host or new URL(baseUrl).hostname.
  • Perform equality checks or use explicit allowed suffix matches (.endsWith()) on the parsed host, rather than unchecked substring search on the whole URL.

This change should be done inside the detectProviderFromConfig method.
Parsing might throw if the URL is malformed, so ideally catch and default to null.
Any includes checks for hosts must be replaced with precise suffix or equality checks on the parsed host/hostname.
No new dependencies are needed, as the Node.js runtime URL class suffices.

How to fix:
Rather than checking if "aliyuncs.com" is a substring anywhere in baseUrl, the code should first parse baseUrl and then check the host component exactly against a whitelist of valid provider domains. This ensures that accidental or malicious inclusion of substrings in other URL fields or superdomains doesn't affect provider detection.

Implementation details:

  • Parse baseUrl to extract the hostname.
  • Check if hostname is exactly one of a whitelist for Qwen provider (e.g., dashscope.aliyuncs.com, aliyuncs.com), or is a subdomain of these.
  • This requires using Node's built-in URL class (in all supported Node versions).
  • Modify lines 186–206 to perform host-based checks instead of substring checks.
  • Add a helper function for subdomain matching.
  • No external dependencies are needed.

To resolve the incomplete substring URL sanitization error, we should parse the baseUrl using the built-in URL constructor and extract the hostname. Then, perform the provider matching by comparing the hostname (and/or subdomain) rather than looking for substrings anywhere in baseUrl. For "deepseek.com", we should match deepseek.com and its direct subdomains (i.e., api.deepseek.com). We similarly update the other substring matches within the function for consistency. Only the function detectProviderFromConfig (lines 179–209) needs to change. We will need to handle parsing errors gracefully.

No new dependencies are needed, as the global URL class is available in Node and browsers.

The best fix is to parse the baseUrl using the standard URL parser (the global URL class in Node.js/TypeScript). Then, verify the host portion directly rather than using a substring search. For all provider checks, replace the current substring matching with explicit comparisons to whitelisted host values (or their exact subdomains if intended). This preserves the intent ("identify if this is DeepSeek, Z.ai, Qwen, etc.") without risk of false positives due to substring matching elsewhere in the URL. Edits needed: in detectProviderFromConfig, replace substring matching checks on baseUrl with checks on host, using the parsed URL. Add the required error handling for malformed URLs.

To fix this issue, the code must properly parse the baseUrl as a URL and then check its hostname (not the entire URL string) against an explicit list of allowed host patterns or known hosts. This should only compare the host portion, not any part of the path, query, or protocol, thus avoiding the incomplete match vulnerability.

Specifically, in file src/api/providers/claude-code.ts, replace the substring .includes(...) approach in the definition of isAlternativeProvider (lines 224-231) with a check that:

  • Uses the URL constructor to parse baseUrl and retrieve its hostname.
  • Checks if the parsed hostname is either exactly one of the allowed hostnames or matches a list of known patterns. (If support for subdomains is needed—for example, anything ending with .aliyuncs.com—we can use endsWith on the hostname.)

No external libraries are needed for this fix as Node.js's standard URL object provides sufficient functionality.

General fix:
Instead of checking if baseUrl includes certain substrings, parse the baseUrl as a URL, extract the hostname, and compare the hostname against an explicit whitelist of trusted hosts (and/or recognized subdomains). Do not use substring comparisons on the whole URL.

Detailed fix:

  • In src/api/providers/claude-code.ts, add an import for Node's built-in url module (import { URL } from "url").
  • Define an array containing the allowed hostnames and subdomains for the alternative providers (e.g. "z.ai", "dashscope.aliyuncs.com", "aliyuncs.com", "deepseek.com", "api.deepseek.com").
  • When evaluating isAlternativeProvider, if baseUrl is present:
    • Parse it with new URL(baseUrl), and extract the hostname.
    • Check whether the host matches any of the allowed hosts, or (optionally) whether it ends with a dot plus the allowed host (to allow subdomains).
  • Update the logic for isAlternativeProvider accordingly, replacing the includes checks with proper host checks.

Additional notes:

  • This only requires importing URL from "url" and modifying the relevant block.
  • Existing functionality will not change—only the safety of the provider selection logic will be improved.

Code scanning / CodeQL

Incomplete URL substring sanitization High

'
api.deepseek.com
' can be anywhere in the URL, and arbitrary hosts may come before or after it.

Copilot Autofix

AI about 2 months ago

General Fix:
Refactor the logic to properly parse the baseUrl using the WhatWG URL class, then extract and compare only the hostname portion against a whitelist of known/allowed hosts (including subdomains, if necessary). The code should no longer use includes on the full URL string.

Detailed Fix:

  • At the site where isAlternativeProvider is set, instead of matching substrings anywhere, extract the actual hostname (e.g., api.deepseek.com) and compare it (via .endsWith or a whitelist includes).
  • Prepare a whitelist/set of allowed hostnames; recommendations from the code are: z.ai, dashscope.aliyuncs.com, aliyuncs.com, deepseek.com, api.deepseek.com.
    • If you intend to allow all subdomains for some root (e.g., *.z.ai), an .endsWith on hostname (with extra logic to block things like maliciousz.ai) is needed.
  • Add import of Node's global URL class if not available in the snippet's context.

File, Line:
In src/api/providers/claude-code.ts, refactor the isAlternativeProvider assignment, replacing lines 224–230, and import any needed definitions at the top.

[P1] Dynamic Claude Code models may not load unless router models are explicitly requested. The debounced refresh posts requestRouterModels for 'litellm' and 'deepinfra' but not for 'claude-code'. If the hook doesn't auto-fetch on mount, users selecting Claude Code won't see alternative provider models. Consider including 'claude-code' in the condition.

Suggested change
// Use type assertion since claude-code is not part of RouterModels type but we add it dynamically
} else if (selectedProvider === "litellm" || selectedProvider === "deepinfra" || selectedProvider === "claude-code") {

[P2] Unused variable. 'provider' from providerInfo is not used and will trigger lint warnings; remove it to keep the code clean.

Review Summary

I've completed a re-review of PR #8453 after the latest security improvements. The new changes add proper URL scheme validation and security attributes to external links, which are good security practices.

Issues Found

The following issues from the previous review remain unaddressed:

  • [P1] Add 'claude-code' to model refresh condition in ApiOptions.tsx:231 to ensure dynamic models load properly
  • [P2] Remove unused 'provider' variable in claude-code.ts:42 to eliminate lint warnings
  • [P3] Remove duplicate 'envVars' type declaration in run.ts:31
  • [P3] Remove duplicate 'envVars' type declaration in run.ts:157
  • [P3] Update return type of getAvailableModels() to remove '| null' since it always returns an object

Latest Changes (5a3a101)

Security Improvements - No new issues found:

  • Added URL scheme validation in webviewMessageHandler.ts to only allow http/https protocols
  • Added rel="noreferrer noopener" security attribute to external link in ApiOptions.tsx

Review Status

Code Quality: The latest security changes are well-implemented. The P1 issue regarding dynamic model loading for claude-code alternative providers should be addressed before merging.

Recommendation: Address the P1 issue to ensure the feature works correctly for all users. The P2 and P3 issues are minor cleanup items that can be addressed at your discretion.

roomote bot commented Oct 21, 2025

CodeQL hardening applied and tests green.

Summary of fixes:

  • Sanitized external URL handling to only allow http/https and added error handling in openExternal.
  • Added rel="noopener noreferrer" to external links in settings UI for safer target=_blank in ApiOptions.
  • Restored platform-specific arg handling to satisfy tests and avoid injection issues in runProcess(): on non-Windows we pass --system-prompt via CLI; on Windows we pass systemPrompt+messages via stdin. Tests confirm expected behavior.

Validation:

  • Backend tests: passed (cd src && npx vitest run).
  • Webview UI tests: passed (cd webview-ui && npx vitest run).

CI/CodeQL:

  • Pushed updates to feat/claude-code-alternative-providers. If CodeQL does not auto-rerun, please trigger “Re-run jobs” for the CodeQL workflow on this PR.

Avoid using inline fallback strings in translation calls. Remove the || default values and rely on the translation system's automatic fallback.
