Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Admidio versions before 5.0.9 have a cross-site request forgery flaw in the preferences module, where the database backup, test email and htaccess generation actions run on GET requests without a CSRF token check. An attacker who gets a logged-in administrator to visit a malicious page can trigger these actions, such as forcing a database dump, overwriting the .htaccess file, or sending test emails from the server. Upgrade to Admidio 5.0.9 or later.
