SCA: security update for admidio/admidio (GHSA-c7xm-r6vj-8vg6)

medium Tenable Self-Hosted Container Security Plugin ID 440981

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Admidio is an open-source user management solution. Prior to version 5.0.9, Role::stopMembership() does
 not verify whether removing a user from the administrator role leaves zero administrators. The deprecated
 Membership::stopMembership() contains this safety check, but the current code path bypasses it. Any
 administrator can remove the last remaining other administrator, locking the entire system out of
 administrative access. The exploit does not require concurrent requests; sequential removals produce the
 same result. This issue has been patched in version 5.0.9. (CVE-2026-41662)

Solution

Update the admidio/admidio library and its related packages to version 5.0.9 or later.
