CVE-2026-41656Admidio: Path Traversal via Unvalidated `name` Parameter in Document Add Mode Enables Arbitrary Server File Read

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, the add mode in modules/documents-files.php accepts a name parameter validated only as 'string' type (HTML encoding), allowing path traversal characters (../) to pass through unfiltered. Combined with the absence of CSRF protection on this endpoint and SameSite=Lax session cookies, a low-privileged attacker can trick a documents administrator into clicking a crafted link that registers an arbitrary server file (e.g., install/config.php containing database credentials) into a documents folder accessible to the attacker. This issue has been patched in version 5.0.9.
