## What is CVE-2026-34382?

CVE-2026-34382 is a medium-severity vulnerability in admidio, published on 31 Mar 2026. Any signed-in user can exploit it over the network, and only if a user opens a file or follows a link.

### Official description

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.

Weakness: CWE-352 (Cross-Site Request Forgery)
