Technical details

The Content Templater, ReReplacer, and Snippets extensions for Joomla fail to consistently implement CSRF tokens, item-level permission checks, and input validation across administrator actions, editor popups, and import/export requests. This vulnerability (CWE-284 and CWE-352) allows unauthorized backend users or remote attackers (via Cross-Site Request Forgery) to expose, create, or modify extension configurations and items. The issue stems from inconsistent enforcement of security controls in the backend components of these extensions. Users should update to versions beyond the affected ranges specified by the vendor.
