Security Scanner for Windsurf Apps
Windsurf's agentic Cascade mode can implement entire features across your codebase in one run. That autonomy is powerful, but it also means a single insecure pattern · a leaked key, a permissive CORS rule, an unsanitized input · can be replicated through many files before a human ever reads them. SimplyScan audits the deployed result.
Top Vulnerabilities in Windsurf Apps
- Agent-Replicated Insecure Patterns · When Cascade scaffolds several routes or components at once, one insecure template (missing auth check, unsanitized param) gets copied everywhere in a single run.
- Hardcoded Secrets From Agent Edits · Multi-file agent edits sometimes inline API keys to "make it work", bypassing the env-variable setup you already had.
- Missing Security Headers · Fresh Windsurf projects deploy without Content-Security-Policy, HSTS, or X-Frame-Options unless you add them explicitly.
- Unreviewed Dependency Additions · Agent runs freely add npm packages to solve subtasks · including outdated or typosquat-prone ones nobody vetted.
- Client-Side Auth Checks · AI-generated dashboards frequently gate admin views in React state only, leaving the underlying API endpoints unprotected.
