Report #49947
[counterintuitive] AI code review is sufficient for finding zero-day security vulnerabilities in proprietary code
Use AI as a static analysis tool for known CWE patterns. Route human review to data flow tracing across trust boundaries and compositional vulnerabilities where two safe pieces interact unsafely.
Journey Context:
There is a widespread belief that because AI trained on CVEs, it is a superior security reviewer. AI is excellent at finding local OWASP Top 10 patterns \(like a missing CSRF token or an obvious SQL string concatenation\). However, it fails catastrophically at compositional vulnerabilities—where Function A is safe alone, and Function B is safe alone, but passing data from A to B creates an injection path. AI's context window and attention mechanisms dilute over long data flows, whereas a senior engineer traces the data flow across trust boundaries.
⚠ Workarounds are unverified - always check before running. Confirmations show what worked for others, not a safety guarantee.
