CVE-2026-32818

MEDIUM CVSS 3.1: 6.5 EPSS 0.04%
Updated Mar 23, 2026
PHP
Parameter Value
CVSS 6.5 (MEDIUM)
Affected Versions 5.0.0 — 5.0.7
Fixed In 5.0.7
Type CWE-862 (Missing Authorization)
Vendor PHP
Public PoC No

Admidio is an open-source user management solution. In versions 5.0.0 through 5.0.6, the forum module in Admidio does not verify whether the current user has permission to delete forum topics or posts. Both the topic_delete and post_delete actions in forum.php only validate the CSRF token but perform no authorization check before calling delete().

Any authenticated user with forum access can delete any topic (with all its posts) or any individual post by providing its UUID. This is inconsistent with the save/edit operations, which properly check isAdministratorForum() and ownership before allowing modifications. Any logged-in user can permanently and irreversibly delete any forum topic (including all its posts) or any individual post by simply knowing its UUID (which is publicly visible in URLs), completely bypassing authorization checks.

This issue has been fixed in version 5.0.7.
