CVE-2023-1885Public exploitNetwork attack vector

Stored script execution via unescaped category names

Published Apr 5, 2023 · Updated Feb 10, 2025

Stored cross-site scripting in phpMyFAQ before 3.1.12 allows remote authenticated users to execute script through a category name. The admin category tree in admin/category.main.php outputs stored category names without HTML-entity conversion. An account able to set a category name can inject browser-executed content when the affected tree is rendered, exposing data or actions available to that browser session.
