Audit Report — Interact Platform

Audit Date: March 2026
Auditor: Automated Codebase Audit
Methodology: Static analysis, npm audit, ESLint, test suite review, file inspection
Scope: Full codebase — frontend (React SPA), backend (Base44 serverless functions), documentation, configuration

Executive Summary

The Interact employee engagement platform is a feature-rich, architecturally sound React 18 + Vite 6 application with Base44 serverless backend. It has grown substantially from its initial release to 117 registered page components and ~200 TypeScript serverless functions across 13 feature domains.

The platform demonstrates strong product completeness but carries technical debt in three areas:

Area Status Priority
Security (npm vulnerabilities) 🔴 9 vulnerabilities (6 high) Fix immediately
Code quality (ESLint errors) 🟠 870 problems (513 errors) This sprint
Test coverage 🟠 Low baseline This sprint

No data loss risks, no architectural showstoppers, and no dead code concerns (beyond one stale backup file).

3. Security Findings (WSJF)

Finding SEC-01: Six High-Severity npm Vulnerabilities

WSJF: 10 | Severity: 🔴 High | Effort: S (1 day)

Detail:

Package Vulnerability CVE
jspdf <=4.1.0 PDF object injection + arbitrary JS execution GHSA multiple
quill 2.0.3 XSS via HTML export GHSA-4pdm-h8vc-3x7c
axios 1.0.0–1.13.4 DoS via __proto__ key pollution GHSA-jr5f-v2jv-69x6
rollup 4.0.0–4.58.0 Arbitrary file write (path traversal) in build GHSA-gcx4-mw62-g8wm
flatted <3.4.0 Unbounded recursion DoS —
minimatch <=3.1.3 Regular Expression DoS (ReDoS) CVE-2022-3517

Risk: The quill XSS and jspdf arbitrary JS execution are the most critical — if user-controlled content reaches these libraries without sanitization, remote code execution in the browser is possible.

Remediation:

npm audit fix
npm install jspdf@latest axios@latest dompurify@latest quill@latest
npm audit  # Verify 0 high vulnerabilities

Finding SEC-02: Two Moderate npm Vulnerabilities

WSJF: 6 | Severity: 🟠 Moderate | Effort: XS (hours)

Package Vulnerability
dompurify 3.1.3–3.3.1 XSS bypass via namespace confusion
ajv <6.14.0 ReDoS via malicious JSON schema

Remediation: npm install dompurify@latest ajv@latest

Finding SEC-03: Missing Content-Security-Policy Header

WSJF: 7 | Severity: 🔴 High | Effort: S (1 day including testing)

Detail: vercel.json defines 5 security headers but is missing CSP — the most effective XSS mitigation available to web applications. Combined with the quill/jspdf XSS vulnerabilities above, the lack of CSP creates significant XSS risk.

Current headers: X-Content-Type-Options, X-Frame-Options, X-XSS-Protection (legacy), Referrer-Policy, Permissions-Policy

Remediation: Add CSP header to vercel.json (start with Report-Only mode).

Finding SEC-04: Missing HSTS Header

WSJF: 4 | Severity: 🟠 Medium | Effort: XS (minutes)

Detail: No Strict-Transport-Security header. While Vercel enforces HTTPS at the edge, HSTS at the browser level prevents downgrade attacks for return visitors.

Remediation: Add Strict-Transport-Security: max-age=63072000; includeSubDomains; preload to vercel.json.

Finding SEC-05: Missing CORP/COOP Headers

WSJF: 3 | Severity: 🟡 Low | Effort: XS (minutes)

Detail: No Cross-Origin-Resource-Policy or Cross-Origin-Opener-Policy headers. These protect against Spectre-class cross-origin data leaks.

Remediation: Add Cross-Origin-Resource-Policy: same-origin and Cross-Origin-Opener-Policy: same-origin.

Finding SEC-06: No SSO / SAML / OIDC

WSJF: 2 | Severity: 🟡 Medium | Effort: XL

Detail: Enterprise customers typically require SSO integration (Okta, Azure AD, Google Workspace). Currently only Base44's own auth is supported.

Remediation: See docs/security/SSO_IMPLEMENTATION.md for planned approach.

4. Code Quality Findings (WSJF)

Finding CQ-01: 513 ESLint Errors (Unused Imports)

WSJF: 8 | Severity: 🟠 Medium | Effort: S

Detail: npm run lint reports 870 total problems: 513 errors and 357 warnings. The vast majority of errors are no-unused-vars / unused-imports/no-unused-imports — imports that were added during development and never removed.

Impact:

  • Masks real errors — developers stop paying attention to lint output
  • Cognitive overhead when reviewing files
  • Minimal bundle size impact (tree-shaking handles most cases)

Breakdown by type:

513 errors   — primarily unused imports
357 warnings — useEffect dependency arrays, missing key props, etc.

Remediation:

npm run lint:fix    # Auto-removes unused imports
npm run lint        # Verify reduced count

Finding CQ-02: React Hooks Violations (Historical)

WSJF: N/A (already fixed) | Status: ✅ Resolved

Detail: Per CHANGELOG.md, 4 React Hooks violations were found and fixed in March 2026:

  • src/Layout.jsx — useMemo called after early return
  • src/components/admin/gamification/EngagementAnalytics.jsx
  • src/components/admin/gamification/SkillDevelopmentTrends.jsx
  • src/components/admin/gamification/UserProgressOverview.jsx

All hooks are now called unconditionally at component top level.

Finding CQ-03: moment.js Usage (Deprecated Library)

WSJF: 1 | Severity: 🟡 Low | Effort: S

Detail: moment.js (v2.30.1) is present as a dependency. It is deprecated by its maintainers, significantly increases bundle size (~300KB), and the project already has date-fns (v3.6.0) installed as a modern replacement.

Remediation: Replace all moment usages with date-fns equivalents, then remove the dependency.

grep -r "from 'moment'" src/ --include="*.jsx" --include="*.js" | wc -l

Finding CQ-04: No TypeScript (JavaScript Codebase)

WSJF: 6 | Severity: 🟠 Medium | Effort: M

Detail: The frontend is entirely JavaScript (.jsx). TypeScript is installed (typescript@5.8.2, @types/* packages, tsconfig.json present) but not yet applied to source files. This increases risk of type-related bugs and reduces IDE assistance.

Migration plan:

  1. Start with src/lib/, src/api/, src/hooks/ (pure utilities, easier to type)
  2. Migrate page components gradually (.jsx → .tsx)
  3. Enable strict mode after initial migration

5. Architecture Assessment

Strengths

Area Assessment
Component architecture ✅ Clean three-tier (Page → Feature → UI Primitive)
State management ✅ TanStack Query for server state; Context for global; RHF for forms
Error handling ✅ ErrorBoundary wraps AuthenticatedApp; loading states throughout
Routing ✅ React Router 6 with SPA catch-all; layout wrapper pattern
Auth ✅ AuthContext abstraction; clean token lifecycle
Build tooling ✅ Vite 6 with code splitting; Rollup visualizer installed
Accessibility ✅ Radix UI primitives provide a11y foundation

Concerns

Area Concern Priority
Bundle size moment.js, three.js, and jspdf are heavy — not lazy loaded Medium
Page count 117 pages is high — route-level code splitting helps but needs verification Low
No E2E tests test:e2e script is a placeholder echo Medium
No monitoring No error tracking service (Sentry, Datadog) integrated Medium

6. Test Coverage Assessment

Current State

Test Suites: 14 passed (14 total)
Tests:       114 passed, 31 skipped (145 total)
Coverage:    Low baseline (< 5% estimated)

Skipped Tests: 31

31 tests are marked skip or todo. These represent deferred work that should be:

  1. Completed if the feature is implemented
  2. Removed if the feature was removed

Action: Review each skipped test; promote to passing or remove.

Coverage Gaps

Area Tests Present Coverage
src/lib/utils.js ✅ Yes ~80%
src/lib/imageUtils.js ✅ Yes ~80%
src/utils/index.js ✅ Yes ~80%
src/hooks/ ✅ Partial ~30%
src/pages/ ❌ None ~0%
src/components/ ❌ None ~0%
src/api/ ❌ None ~0%

Target: 30% line coverage by end of Q1 2026.

7. Documentation Assessment

Existing Documentation (Strong)

The project has extensive documentation in docs/ with 40+ files covering:

  • Security framework (7 docs in docs/security/)
  • Architecture and planning (12 docs in docs/planning/)
  • Operations and guides
  • Multiple audit reports

Gaps Addressed by This Audit

This audit added 9 new documentation files:

File Purpose
docs/DEAD-CODE-TRIAGE.md Backup file analysis and ESLint triage
docs/ARCHITECTURE.md System architecture overview
docs/API.md API reference (entities + functions)
docs/PRD.md Current-state product requirements
docs/ROADMAP.md WSJF-scored technical roadmap
docs/RUNBOOK.md Operational procedures
docs/DATABASE.md Full 39-entity schema documentation
docs/SECURITY.md Security posture and remediation guide
docs/AUDIT-REPORT.md This document

8. Dead Code Analysis

Finding DC-01: Stale Backup File

WSJF: 9 | Severity: 🟠 Low risk, but should be removed | Effort: XS

File: src/pages.config.js.backup (293 lines)
Current file: src/pages.config.js (313 lines)

The backup is an older snapshot of the pages configuration, missing 10+ pages added since. It has no functional role.

Decision: KEEP_CURRENT — delete the backup file.

rm src/pages.config.js.backup

Full analysis: See docs/DEAD-CODE-TRIAGE.md.

Finding DC-02: No Other Dead Code Found

A review of the source tree found no other dead code concerns:

  • All 117 pages are imported and registered in pages.config.js
  • The src/modules/ example module is documented as a reference implementation
  • Functions directory contents are all active serverless functions
