WordPress · Download Manager · CVE-2026-4057
Name of the Vulnerable Software and Affected Versions
Download Manager plugin for WordPress versions up to and including 3.3.51
Description
The Download Manager plugin for WordPress is susceptible to unauthorized data modification. This is due to a missing capability check in the `makeMediaPublic()` and `makeMediaPrivate()` functions. These functions only verify the `edit posts` capability, failing to confirm post ownership using `current user can('edit post', $id)`. The destructive operations occur before the admin-level check in `mediaAccessControl()`. Authenticated attackers with Contributor-level access or higher can remove protection metadata (passwords, access restrictions, private flags) from any media file, even those they do not own, making admin-protected files publicly accessible via their direct URL.
Recommendations
Update to a version beyond 3.3.51.
