How to Fix CVE-2026-76210

To remediate this vulnerability, upgrade all affected Software dependencies to a patched release. Both direct and transitive dependencies should be checked, as frameworks or security libraries may pull in vulnerable versions transitively.

Verify Direct and Transitive Dependencies

Run the following command in your project directory to verify that all resolved dependencies use the patched release: 

mvn dependency:tree

How to Check if You Are Affected

To determine whether your Java application is affected by CVE-2026-76210, inspect your build dependencies using the Maven Dependency Plugin:

mvn dependency:tree

Analyze the terminal output to locate any version of Software in your dependency tree. If any resolved version matches the vulnerable ranges listed in the table below (for example, versions earlier than the patched release), your application is affected.

Note: The mvn dependency:tree command inspects the resolved dependency graph declared in your project's POM files; it does not perform automated security scanning or inspect runtime dynamic classpaths. Always verify runtime container classpaths and shaded JARs.

Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under CWE-73: External Control of File Name or Path, where the product allows user input to control or influence paths or file names that are used in filesystem operations. In Software, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

phpMyFAQ before 4.1.7 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.
