Summary
phpMyFAQ before version 4.1.7 fails to persist the WebAuthn login challenge, allowing an attacker who captures a successful WebAuthn assertion to replay it indefinitely and authenticate as the user without interaction or hardware key.
Risk Assessment
An attacker can take over a user's account without knowing the password or possessing the hardware key, leading to unauthorized access to application data and functions.
Recommendation
Upgrade phpMyFAQ to version 4.1.7 or later, which includes a fix preventing the anti-replay comparison from being skipped.
Other vulnerabilities in phpMyFAQ
See all- CVE-2026-56736High
phpMyFAQ is an open source FAQ web application. A stored cross-site scripting (XSS) vulnerability in versions prior to 4.2.0-alpha allows any unauthenticated user (or low-privileged registered user) to inject arbitrary JavaScript that executes in an administrator's browser when they review or edit a user-submitted FAQ entry. This leads to admin account takeover via session theft.
- CVE-2026-57994Medium
A vulnerability in phpMyFAQ before version 4.1.5 allows unauthenticated attackers to retrieve inactive (draft or review-only) FAQ content due to inconsistent filtering in public API endpoints.
- CVE-2026-57961Low
phpMyFAQ before version 4.1.5 contains a path traversal vulnerability in the concatenatePaths() function in Wrapper.php. An authenticated user with FAQ editing privileges can store crafted HTML with image paths that are processed during PDF generation. Lack of path canonicalization and root-directory containment validation may allow reading files outside the intended content directory.

Original NVD description (English source)
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.
