CVE-2025-0818

Several WordPress plugins using elFinder versions 2.1.64 and prior are vulnerable to Directory Traversal in various versions. This makes it possible for unauthenticated attackers to delete arbitrary files. Successful exploitation of this vulnerability requires a site owner to explicitly make an instance of the file manager available to users.
