CVE-2026-14982: WP File Download <= 6.3.4 - Authenticated (Subscriber+) Arbitrary File Deletion via 'remoteurl' Parameter
The WP File Download plugin for WordPress is vulnerable to arbitrary file deletion due to insufficient file path validation in the delete function in all versions. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete arbitrary files on the server, which can easily lead to remote code execution when the right file is deleted (such as wp-config.php). The two-stage exploit requires a first request to the file.save task to persist the path-traversal string into file metadata, followed by a second request to the file.delete task to trigger the unlink call — both endpoints lack capability checks and nonce enforcement.

Frequently Asked Questions
Which accounts can exploit this issue?
Any authenticated account with subscriber-level access or higher can exploit it. The affected endpoints do not enforce capability checks or nonce validation.
What does exploitation require?
Exploitation requires two requests: one to file.save to store a path-traversal value in file metadata, then one to file.delete to cause the server to delete the referenced file. No user interaction is required.
Are sites using the plugin's default access controls protected?
No. Subscriber-level access is sufficient, and the vulnerable endpoints lack both capability checks and nonce enforcement.
What is the likely impact if exploitation succeeds?
An attacker can delete arbitrary files on the server. Deleting a file such as wp-config.php can potentially lead to remote code execution.
