CVE-2026-41663Admidio: CSRF on Admin Preferences Triggers Unauthorized Backup, .htaccess Write, and Email Send

Does this affect you?

It affects admidio. Add what you run to find out whether that includes you.

No exploitation reported and no EPSS estimate yet.

Admidio is an open-source user management solution. Prior to version 5.0.9, several administrative operations in Admidio's preferences module (database backup, test email, htaccess generation) fire via GET requests with no CSRF token validation. Because SameSite=Lax cookies travel with top-level GET navigations, an attacker forces an authenticated admin to trigger these actions from a malicious page. This issue has been patched in version 5.0.9.
