Arbitrary File Deletion Vulnerability in WP User Manager Plugin by WordPress

CVE-2025-13320

What is CVE-2025-13320?

The WP User Manager plugin for WordPress has a flaw that allows authenticated users to delete arbitrary files on the server due to improper validation in the profile update process. This vulnerability arises from insufficient checks on user-supplied file paths and flawed handling of PHP array inputs, primarily affecting installations where the custom avatar feature is active. Attackers with Subscriber-level access and higher can exploit this issue, potentially paving the way for remote code execution through a multi-step attack process.
