{"id":"CVE-2026-56736","published":"2026-09-24T15:17:24.100","lastModified":"2026-09-24T15:17:24.240","description":"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. The vulnerability exists because `html_entity_decode()` converts HTML entities into executable HTML after `strip_tags()` has already passed them through, and the admin template renders the content with Twig's `|raw` filter without any output sanitization. Version 4.2.0-alpha fixes the issue.","cvssScore":8.2,"cvssSeverity":"HIGH","cvssVector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:L/A:N","cwes":["CWE-79"],"vendors":[],"products":[],"references":[{"url":"https://github.com/thorsten/phpMyFAQ/security/advisories/GHSA-pgwp-vc7q-cvj3","tags":[]},{"url":"https://github.com/thorsten/phpMyFAQ/security/advisories/GHSA-pgwp-vc7q-cvj3","tags":[]}],"exploitRefs":[{"url":"https://github.com/thorsten/phpMyFAQ/security/advisories/GHSA-pgwp-vc7q-cvj3","tags":[]},{"url":"https://github.com/thorsten/phpMyFAQ/security/advisories/GHSA-pgwp-vc7q-cvj3","tags":[]}],"hasPoc":true,"ai":null}
