Admidio is an open-source user management solution. From version 5.0.0 to before version 5.0.8, the delete mode handler in mylist_function.php permanently deletes list configurations without validating a CSRF token. An attacker who can lure an authenticated user to a malicious page can silently destroy that user's list configurations — including organization-wide shared lists when the victim holds administrator rights. This issue has been patched in version 5.0.8.
