CVE-2021-39312Public exploitNetwork attack vector

Arbitrary file read via unsanitized src path

Published Dec 14, 2021 · Updated Jan 31, 2025

Path traversal in True Ranker 2.2.2 and earlier allows remote attackers to read arbitrary server files through an exposed plugin endpoint. The admin/vendor/datatables/examples/resources/examples.php script accepts a POSTed src path and resolves traversal segments without restricting the result to its intended resources directory. No authentication or user interaction is required, and disclosure is limited to files readable by the WordPress server process, including wp-config.php.
