Greptile Summary

  • Comprehensive security fix adding authentication to 30+ previously unprotected API routes including function execution, database tools (MySQL, PostgreSQL), SSH operations, and provider endpoints
  • Implements SSRF protection with validateExternalUrl() and DNS pinning for push notifications and external webhook configurations to prevent malicious URL exploitation
  • Introduces safeAssign() utility to replace Object.assign() across the codebase, preventing prototype pollution attacks from user-controlled data

Important Files Changed

Filename Overview
apps/sim/tools/safe-assign.ts New utility function to prevent prototype pollution by filtering dangerous keys (proto, constructor, prototype) during object assignment
apps/sim/app/api/function/execute/route.ts Added critical authentication check to function execution endpoint that was previously open to arbitrary code execution
apps/sim/app/api/a2a/agents/[agentId]/route.ts Added workspace access validation to prevent IDOR vulnerabilities in A2A agent management endpoints
apps/sim/lib/a2a/push-notifications.ts Implemented SSRF protection with DNS validation and IP pinning for push notification webhook URLs

Confidence score: 4/5

  • This PR significantly improves security posture by addressing critical vulnerabilities across authentication, SSRF, and prototype pollution attack vectors
  • Score reflects minor concern with timeout parameter change in secure fetch implementation that may not be compatible with the new API (line 74 in push-notifications.ts)
  • Most changes require careful review due to their security-critical nature, particularly the authentication implementations and SSRF protections

When copilot.host equals realtime.host but differs from app.host,
copilot paths were not being routed. Added logic to consolidate
copilot paths into the realtime rule for this scenario.
