CVE-2023-23750Network attack vector

Forced administrator actions via missing token check

Published Feb 1, 2023 · Updated Mar 29, 2025

CSRF in Joomla! CMS 4.0.0 through 4.2.6 allows remote attackers to submit post-installation-message actions through an administrator's browser. The post-installation-message handler processes state-changing requests without verifying Joomla's form token; the vendor has not identified the affected function or enumerated every action. Exploitation requires an authenticated administrator to interact with attacker-controlled content, and the published record bounds the result to post-installation-message handling.
