SCA: security update for admidio/admidio (GHSA-gq27-fc8w-vcmp)

medium Tenable Cloud Security Plugin ID 440982

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, an unauthenticated attacker
can execute arbitrary JavaScript in any Admidio user's browser through a reflected XSS in
system/msg_window.php. The endpoint passes user input through htmlspecialchars(), which does not encode
square brackets. A subsequent call to Language::prepareTextPlaceholders() converts those brackets into
HTML angle brackets, producing executable markup. This issue has been patched in version 5.0.9.
(CVE-2026-41661)

Solution

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