AI Reviewers Approve Malicious Code Due to "Pre-Approved" Label

Security researchers have exposed a flaw in AI-based code review systems. The systems allowed code containing secret exfiltration to be shipped. This occurred because the pull request was labeled as "pre-approved." The AI relied on the text label rather than analyzing the actual code. This demonstrates a blind spot in automated security verification tools. It highlights the danger of implicit trust in metadata over content analysis. The experiment shows how easily automation can be bypassed by simple social engineering. Developers are warned to verify code regardless of automated approval status.
