DescriptionCVE.org

The Simple File List WordPress plugin through 6.3.11 does not validate the source path of a file-move operation reachable by unauthenticated users, allowing them to read arbitrary files on the server and to relocate critical files out of the web root, leading to sensitive information disclosure and potential site takeover.

AnalysisAI

Unauthenticated path traversal in the Simple File List WordPress plugin (versions through 6.3.11) exposes an unvalidated file-move endpoint accessible without authentication, enabling arbitrary server file reads and displacement of critical WordPress files outside the web root. Remote attackers can exfiltrate sensitive data such as wp-config.php database credentials and secret keys, and can displace core WordPress files to cause site failure or enable site takeover. …
