CVE-2026-76214

phpMyFAQ versions before 4.1.7 (affected ≤ 4.1.5) contain a WebAuthn replay attack vulnerability. The root cause is that the login challenge generated by prepareForLogin is never persisted to the database because neither WebAuthn controller saves the mutated key objects. As a result, the anti-rep...
