CVE-2026-41663 Details
Description
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.
A Cross-Site Request Forgery (CSRF) vulnerability has been identified in Admidio's preferences module, affecting versions through 5.0.8. Several administrative operations, including database backup, test email sending, and .htaccess file generation, are executed via GET requests without proper CSRF token validation. This oversight allows an attacker to exploit authenticated administrators by forcing them to perform these actions from a malicious webpage. The vulnerability arises because 'SameSite=Lax' cookies are sent with top-level GET requests, enabling CSRF exploitation.
Users are advised to update to Admidio version 5.0.9 or later, where this vulnerability has been patched.
