Summary
phpMyFAQ 4.2.0-alpha before 4.2.0-beta contains an authentication bypass vulnerability that allows Keycloak users to take over local accounts by matching preferred_username or email. Attackers controlling a Keycloak identity with a colliding username or unverified email can log in through /auth/keycloak/authorize to bind their subject and gain superadmin privileges.
Risk Assessment
The flaw allows an attacker to take over local accounts, including superadmin, via username or email collision in Keycloak, leading to full system control.
Recommendation
Upgrade phpMyFAQ to version 4.2.0-beta or later. Verify Keycloak configuration and ensure emails are verified before account binding.
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.
- CVE-2026-35676High
phpMyFAQ before 4.1.3 contains an unauthenticated password reset vulnerability in the user password update API endpoint that allows attackers to change account passwords without token validation.
- CVE-2026-46367High
phpMyFAQ before version 4.1.2 contains a stored cross-site scripting vulnerability in the Utils::parseUrl() function. This allows authenticated users to inject JavaScript via malformed URLs in comments.
- CVE-2026-46366High
phpMyFAQ before version 4.1.2 contains an information disclosure vulnerability in the getIdFromSolutionId() method that lacks permission filtering. This allows unauthenticated attackers to enumerate restricted FAQ entries and read their titles via the /solution_id_{id}.html endpoint.
- CVE-2026-46359High
phpMyFAQ before version 4.1.2 contains a SQL injection vulnerability in CurrentUser::setTokenData that allows authenticated attackers to execute arbitrary SQL by injecting malicious OAuth token claims.
- CVE-2017-15808High
In phpMyFaq before version 2.9.9, there is a CSRF vulnerability in admin/ajax.config.php.
- CVE-2017-15735High
In phpMyFAQ before version 2.9.9, there is a Cross-Site Request Forgery (CSRF) vulnerability that allows modification of a glossary.
- CVE-2017-15734High
In phpMyFAQ before version 2.9.9, there is a Cross-Site Request Forgery (CSRF) vulnerability in admin/stat.main.php.
