Summary
phpMyFAQ versions before v4.1.6 fail to validate the security.enableRegistration setting in API endpoints, allowing attackers to create user accounts when registration is disabled. Attackers can bypass the registration restriction by submitting requests to POST /api/register or POST /api/v3.1/register endpoints, which do not check the configuration flag enforced by the HTML registration page.
Risk Assessment
The risk is unauthorized creation of user accounts, which could lead to unauthorized access to the system and potential data security breaches.
Recommendation
It is recommended to immediately upgrade phpMyFAQ to version 4.1.6 or later, which includes a fix for the registration validation in the API.
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.
