What we check for

High2026-10-24

StageIt (com_stageit) 5.x below 5.8.0 and 6.x below 6.4.0 - CSRF on every action, PHP Code Injection via Options, Backup Path Traversal and XSS

StageIt before 5.8.0 (Joomla 5 line) and before 6.4.0 (Joomla 6 line) had no CSRF token check on any action (build, push, remove, restore and delete backups, save Options, clear logs), so another website could trigger them through a logged-in administrator's browser. A setting containing an apostrophe could break out of the settings file params.php and run as PHP, the backup delete and restore actions accepted any folder path, the StageIt bar links and the tab parameter allowed reflected XSS, and any visitor could switch the StageIt bar off. Fixed in 5.8.0 and 6.4.0 (24 Oct 2026). No CVE published; severity is mySites.guru's own assessment. StageIt 4.x and earlier (Joomla 3/4) received no fix and are not covered by this rule because their code has not been checked.

Affected versions: ≥ 5.0.0 and < 5.8.0
