Low risk1th percentile - higher than 1% of all known CVEs
Summary
phpMyFAQ through 4.1.10 contains a missing authorization vulnerability in the MCP server faq_search tool that allows MCP clients to read restricted FAQs because Search::searchDatabase() never applies user or group permission checks. Attackers connected to the phpmyfaq:mcp:server can issue search queries to retrieve the full question and answer text of active FAQs restricted to specific users or groups.
Risk Assessment
The risk is unauthorized access to sensitive FAQ content, potentially violating information confidentiality and access control policies.
Recommendation
It is recommended to immediately upgrade phpMyFAQ to a version newer than 4.1.10, implement permission checks in the searchDatabase function, and restrict access to the MCP server.
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.
