Report #95296

[agent\_craft] Agent writes functional code that introduces security vulnerabilities without flagging them

Apply secure-by-default principles when generating code. Never hardcode credentials, always use parameterized queries, always validate input, always prefer HTTPS over HTTP. When the simplest implementation would be insecure, provide the secure version and briefly note why. Flag security-relevant decisions with comments. This isn't over-refusal — it's responsible code generation.

Journey Context:
This aligns with NIST AI RMF's 'Measure' function \(assessing AI system trustworthiness characteristics in deployment\) and OWASP's broader secure coding guidance. The failure mode is 'helpful but dangerous' — code that works but creates attack surface. The counterargument is 'the user asked for a quick prototype, not production code.' But code has a way of becoming production, and insecure defaults propagate through copy-paste. The practical middle ground: always generate secure code, but if the secure version is significantly more complex, provide both with clear labeling \('quick prototype — not for production' vs 'production-ready with security hardening'\). Never silently generate insecure code. The few extra lines are worth the prevented vulnerability.
