CVE-2026-4057: Download Manager <= 3.3.51 - Missing Authorization to Authenticated (Contributor+) Media File Protection Removal
- Severity: medium (CVSS 4.3 v3.1)
- Exploited in the wild: not listed in CISA KEV
- EPSS: 0.4% probability of exploitation in the next 30 days
- Public exploit or detection template: none known
- Published: 2026-04-10 · updated 2026-06-17
- Weakness: CWE-862
Description
The Download Manager plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `makeMediaPublic()` and `makeMediaPrivate()` functions in all versions up to, and including, 3.3.51. This is due to the functions only checking for `edit_posts` capability without verifying post ownership via `current_user_can('edit_post', $id)`, and the destructive operations executing before the admin-level check in `mediaAccessControl()`. This makes it possible for authenticated attackers, with Contributor-level access and above, to strip all protection metadata (password, access restrictions, private flag) from any media file they do not own, making admin-protected files publicly accessible via their direct URL.
