CVE-2020-10238Network attack vector

Unauthorized template actions via missing ACL checks

Published Mar 16, 2020 · Updated Aug 4, 2024

Incorrect access control in Joomla! CMS 2.5.0 through 3.9.15 allows remote attackers to invoke restricted com_templates actions. The component permits template-management actions without the required ACL authorization checks, placing protected resources outside their intended permission scope. No login or user interaction is required; NVD limits the assessed impact to information disclosure, while Joomla does not identify the affected actions.
