Codex Security (formerly Aardvark)

OpenAI renamed Aardvark to Codex Security and opened a research preview to ChatGPT Pro, Enterprise, Business and Edu customers. OpenAI reports that in 30 days it scanned over 1.2 million commits in its beta cohort and flagged 792 critical and 10,561 high-severity findings, that beta changes cut false positives by more than 50%, and that its open-source reports led to 14 CVEs.

OpenAI announced Aardvark, a GPT-5-powered agent in private beta that builds a threat model of a repository, scans commits, tries to trigger suspected flaws in a sandbox, and attaches Codex-generated patches for human review. OpenAI reports 92% recall on known and synthetically introduced vulnerabilities in its 'golden' repositories and ten CVEs from open-source scanning, and planned pro-bono scanning for some non-commercial projects.
