- Replaced detailed upstream service errors and internal stack traces with generic "Internal server error" messages in `src/pages/api/*` routes. - Maintained server-side logging (`console.error`) of the exact details for observability. - Created security journal entry recording the secure API proxy error handling pattern.

🚨 Severity: MEDIUM
💡 Vulnerability: API routes were leaking detailed stack traces, internal errors (
err.message), and full upstream service response bodies back to the client in HTTP 500/502 responses.🎯 Impact: Detailed error messages can inadvertently expose sensitive information such as server configurations, framework details, or upstream credentials to attackers. Since the
src/pages/api/serverless functions act as proxies to Cloudflare AI and Google AI Studio, they were prime targets for extracting sensitive downstream interactions.🔧 Fix: Implemented the "fail securely" principle by ensuring API
catchblocks or failure conditions log detailed error contexts server-side (usingconsole.error) but return strictly generic, non-descriptive JSON error messages to the client.✅ Verification: Verified by checking git diff of
src/pages/api/, ensuring.jules/sentinel.mdjournal entry was correctly created, and running thepnpm run checkpipeline to confirm no regressions.PR created automatically by Jules for task 14008359569569518435 started by @fysp11
