CVE-2026-15991

Name of the Vulnerable Software and Affected Versions File Manager for WordPress versions 6.0 through 6.9

Description Insufficient file path validation in the connector function allows authenticated attackers with subscriber-level access and above to read and delete arbitrary files on the server. This can lead to remote code execution if critical files, such as wp-config.php, are deleted. The issue occurs because the elFinder bind registration reads commands exclusively from $ POST, failing to register the rm.pre permission handler, while the dispatcher uses a merged $ GET and $ POST superglobal. This allows a bypass by passing cmd=rm or cmf=file in the URL query string of a POST request, executing the command unchecked against a volume defaulting to ABSPATH.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability.
