AI Found 7 Bugs in Cloudflare CIRCL: What zkSecurity's zkao Audit Reveals
On July 7, 2026, zkSecurity reported that its LLM pipeline and zkao audit agent confirmed seven real vulnerabilities in Cloudflare's CIRCL cryptography library, all since fixed upstream. They included float64 precision loss in threshold RSA, a BLS rogue-key flaw and a CP-ABE access-control break found by zkao. The AI often misjudged severity, so human triage stayed the bottleneck across 200+ scanned projects and over 1000 candidate findings.
