CVE-2026-56737

phpMyFAQ before 4.1.6 has a vulnerability in the StopWords::add() method that builds a SQL INSERT statement using sprintf() and inserts the user-supplied stop word value directly into the query without calling the database escaping function. An authenticated administrator can submit a crafted value that breaks out of the SQL string literal and injects arbitrary SQL, including dropping tables, exfiltrating data, or modifying other rows.

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.

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.

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.

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.

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.

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.

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.
