The vulnerability affects phpMyFAQ versions prior to 4.1.7, where the WebAuthn login challenge is not properly persisted, allowing attackers to exploit this flaw. By capturing a successful WebAuthn assertion, an attacker can indefinitely replay it to authenticate as the user, bypassing the need for user interaction or a hardware key. Organizations using affected versions should prioritize patching to mitigate the risk of unauthorized access.

Original NVD Description

phpMyFAQ before 4.1.7 fails to persist the WebAuthn login challenge generated by prepareForLogin, because neither WebAuthn controller saves the mutated key objects back to the database. At login the anti-replay comparison is skipped by its own null guard, allowing an attacker who captures a successful WebAuthn assertion to replay it indefinitely and authenticate as the user without any interaction or hardware key.
