CVE-2022-3361Network attack vector

Authenticated file inclusion via shortcode template

Published Nov 29, 2022 · Updated Apr 8, 2026

Path traversal in Ultimate Member through 2.5.0 allows remote authenticated users to read or include arbitrary files via a shortcode template attribute. The shortcode loader passes the template value into a PHP filename and, in affected releases, fails to confine the resolved path to the plugin or theme template directories. Administrative privileges are normally required, although lower-privilege users with wp-admin access can reach the path; including an uploaded PHP file can escalate the impact to remote code execution.
