CVE-2026-57961 phpMyFAQ CVE debrief
A path traversal vulnerability exists in phpMyFAQ before 4.1.5. The vulnerability is located in the concatenatePaths() function within src/phpMyFAQ/Export/Pdf/Wrapper.php. A user with FAQ editing privileges can store HTML containing crafted image paths that are processed during PDF generation. The path resolution logic locates the substring 'content' within a user-controlled path using strpos(); when 'content' is absent, strpos() returns false, which becomes 0 when cast to an integer, preserving the entire attacker-controlled path.

Who should care
Users of phpMyFAQ before version 4.1.5 who have FAQ editing privileges should be aware of this vulnerability. This vulnerability may allow reading of files outside the intended content directory.
Technical summary
The concatenatePaths() function in src/phpMyFAQ/Export/Pdf/Wrapper.php does not properly validate user-controlled paths during PDF generation. Specifically, it uses strpos() to locate the substring 'content' within the path. If 'content' is not found, strpos() returns false, which is then cast to an integer (0), allowing the entire attacker-controlled path to be preserved. This path is later passed to file_get_contents() without proper canonicalization or root-directory containment validation.
Defensive priority
Medium priority should be given to updating phpMyFAQ to version 4.1.5 or later. Users with FAQ editing privileges should be cautious when storing HTML containing image paths.
Recommended defensive actions
- Update phpMyFAQ to version 4.1.5 or later
- Restrict FAQ editing privileges to trusted users
- Monitor PDF generation and file access for suspicious activity
- Implement additional validation and sanitization of user-controlled paths
- Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
- Review compensating controls for exposed systems while remediation is scheduled and verified
- Check relevant monitoring, detection, and logs for exposed assets that need extra review
