CVE-2026-30452
Textpattern CMS 4.9.0 contains a Broken Access Control vulnerability in the article management system that allows authenticated users with low privileges to modify articles owned by users with higher privileges.
Does this matter?
Lower severity and a low EPSS score (0.25%). Track it; it rarely justifies an emergency change on its own.
Description
Textpattern CMS 4.9.0 contains a Broken Access Control vulnerability in the article management system that allows authenticated users with low privileges to modify articles owned by users with higher privileges. By manipulating the article ID parameter during the duplicate-and-save workflow in textpattern/include/txp_article.php, an attacker can bypass authorization checks and overwrite content belonging to other users.
