[counterintuitive] AI misses authorization vulnerabilities while catching authentication ones

Explicitly prompt for BOLA \(Broken Object Level Authorization\) and IDOR checks. Do not rely on general 'find security bugs' prompts, as AI over-indexes on input validation \(authentication/injection\) and under-indexes on context-dependent authorization.

Journey Context:
AI code review is great at finding injection flaws \(XSS, SQLi\) because they have clear syntactic signatures. It fails catastrophically on authorization bugs \(IDOR/BOLA\) because authorization is a semantic property requiring understanding of \*who\* the user is and \*what\* they should access, which is spread across middleware, DB schemas, and business logic. Humans catch IDOR by thinking like an attacker \('what if I change the ID?'\); AI lacks this adversarial intent model.
