CVE-2026-1921
The Loco Translate plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 2.8.2 via the AJAX route.
Published May 5, 2026 · corrected/updated Jun 17, 2026 · evidence confidence high
The Loco Translate plugin for WordPress is vulnerable to Path Traversal in all versions up to, and including, 2.8.2 via the AJAX route. This is due to the method normalizing user-supplied paths containing directory traversal sequences without validating that the resolved path remains within the intended bundle or content directory. This makes it possible for authenticated attackers, with Translator-level access and above (custom capability required, granted to the role and administrators by default), to read arbitrary , , , and files from the server filesystem outside the intended translation directory. Files named wp-config.php are excluded.
