Summary
phpMyFAQ before 4.1.6 does not adequately sanitize HTML in FAQ answers before generating PDFs via TCPDF. An attacker with permission to create or edit FAQ content can embed an <img> tag whose src references a local file under the web root's content/ directory. When the PDF is generated, phpMyFAQ attempts to read the referenced file; because it is not a valid image the resulting error is converted into an uncaught exception whose stack trace discloses part of the file's contents to any user who triggers the PDF export. By default the disclosed portion is truncated, but a larger configured value can result in disclosure of entire files, including database credentials.
Risk Assessment
The vulnerability can lead to disclosure of sensitive data such as database credentials, potentially allowing an attacker full access to the system.
Recommendation
Update phpMyFAQ to version 4.1.6 or later and restrict permissions to create and edit FAQ content.
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.
Original NVD description (English source)
phpMyFAQ before 4.1.6 does not adequately sanitize HTML in FAQ answers before generating PDFs via TCPDF. An attacker with permission to create or edit FAQ content can embed an <img> tag whose src references a local file under the web root's content/ directory (e.g., content/core/config/database.php). When the PDF is generated, phpMyFAQ attempts to read the referenced file; because it is not a valid image the resulting error is converted into an uncaught exception whose stack trace discloses part of the file's contents to any user who triggers the PDF export. By default the disclosed portion is truncated (zend.exception_string_param_max_len), but a larger configured value can result in disclosure of entire files, including database credentials.
