CVE-2026-57994 phpMyFAQ CVE debrief

Who should care

Administrators and users of phpMyFAQ versions before 4.1.5 should be aware of this vulnerability and take necessary actions to protect their systems. Specifically, they should review their current API endpoint configurations, monitor API usage for suspicious activity, and consider implementing additional security measures such as authentication and authorization for API endpoints. Furthermore, they should prioritize patching this vulnerability and verify the affected scope and severity with the official CVE record and NVD entry.

Technical summary

The vulnerability exists in the public FAQ API endpoints of phpMyFAQ, specifically in the GET /api/v3.1/faq/{categoryId}/{faqId}, GET /api/v3.1/faqs/tags/{tagId}, and GET /api/v4.0/faqs/tags/{tagId} endpoints. These endpoints return inactive FAQ content, including titles and full answers or previews, to unauthenticated attackers due to inconsistent active=yes and publication-date filtering. This allows attackers to retrieve inactive (draft or review-only) FAQ content. The vulnerability affects phpMyFAQ versions before 4.1.5 and has a CVSS score of 6.9, with a severity rating of MEDIUM.

Defensive priority

Medium priority should be given to patching this vulnerability, as it allows for the disclosure of non-public content and may impact the security of phpMyFAQ deployments. Administrators and users of phpMyFAQ versions before 4.1.5 should be aware of this vulnerability and take necessary actions to protect their systems. The vulnerability can be mitigated by patching phpMyFAQ to version 4.1.5 or later, reviewing and updating API endpoint configurations, monitoring API usage for suspicious activity, and implementing additional security measures such as authentication and authorization for API endpoints. However, defenders should verify the affected scope and severity with the official CVE record and NVD entry before taking action. The CVE record and NVD entry provide limited information about the vulnerability, and defenders should be cautious when assessing the vulnerability's impact. To address this vulnerability, defenders should consider implementing compensating controls, such as monitoring and detection, and review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance. Additionally, defenders should plan vendor-supported updates or mitigations through normal change control where exposure is confirmed and track exceptions, retest remediated assets, and close the item only after evidence is documented. This vulnerability may impact the security of phpMyFAQ deployments, and defenders should take necessary actions to protect their systems. The vulnerability's impact can be mitigated by implementing additional security measures, such as authentication and authorization, for API endpoints and reviewing compensating controls for exposed systems while remediation is scheduled and verified. Defenders should also check relevant monitoring, detection, and logs for exposed assets that need extra review and confirm whether affected product deployments exist in managed environments and assign an owner for follow-up. To ensure the security of phpMyFAQ deployments, defenders should prioritize patching this vulnerability and take necessary actions to protect their systems. The vulnerability's severity rating and CVSS score are,

Recommended defensive actions

• Patch phpMyFAQ to version 4.1.5 or later
• Review and update API endpoint configurations to ensure proper filtering
• Monitor API usage for suspicious activity
• Consider implementing additional security measures, such as authentication and authorization, for API endpoints
• Confirm whether affected product deployments exist in managed environments and assign an owner for follow-up
• Review the supplied official advisory or CVE record to validate affected scope, severity, and vendor guidance
• Plan vendor-supported updates or mitigations through normal change control where exposure is confirmed
