CVE-2026-27741Public exploitNetwork attack vector

Administrative changes via cross-site request forgery

Published Feb 23, 2026 · Updated Feb 23, 2026

CSRF in Bludit 3.16.1 and earlier allows remote attackers to uninstall plugins or install themes through an administrator's browser. The /admin/uninstall-plugin/ and /admin/install-theme/ handlers accept state-changing requests without anti-CSRF tokens or origin validation. Exploitation requires an authenticated administrator to visit an attacker-controlled page, enabling unauthorized plugin removal or theme installation.
