CVE-2026-76210 thorsten CVE debrief
CVE-2026-76210 is a vulnerability in phpMyFAQ before version 4.1.6 that allows for local file disclosure via PDF export. 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. Organizations using phpMyFAQ, especially those with sensitive data stored in the content/ directory, should prioritize patching to prevent potential local file disclosure via PDF export. The CVE record was published on 2026-08-19T14:17:46.510Z and has not been modified since then.
