CVE-2026-53760
In versions 5.0.11 and prior, the modules/plugins.php endpoint handles plugin installation, uninstallation, and update operations via GET requests without CSRF token validation.
Does this matter?
Lower severity and a low EPSS score (0.17%). Track it; it rarely justifies an emergency change on its own.
Description
Admidio is an open-source user management solution. In versions 5.0.11 and prior, the modules/plugins.php endpoint handles plugin installation, uninstallation, and update operations via GET requests without CSRF token validation. Because these are top-level navigations, browsers include SameSite=Lax session cookies. An attacker crafts a malicious page that, when an authenticated administrator visits it, triggers arbitrary plugin operations. The uninstall operation executes DROP TABLE SQL scripts and destroys plugin data. This issue has been patched via commit 056b1bd.
