CVE-2026-53760Admidio: CSRF on Plugin Install, Uninstall, and Update via Unprotected GET Requests
Medium 5.2
In plain English
A medium-severity cross-site request forgery in admidio from Admidio. Proof-of-concept exploit code is public. The chance it is exploited in the next 30 days is estimated at 0.2% (higher than 6% of all known vulnerabilities).
Official 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.
