Description
The Download Manager plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 3.3.68 via the duplicate() function hooked on admin_init. This is due to the handler only verifying the generic 'edit_posts' capability and a plugin-wide static nonce (NONCE_KEY) without any object-level authorization check against the targeted wpdmpro package ID. This makes it possible for authenticated attackers, with Author-level access and above, to duplicate arbitrary Download Manager packages owned by other users (including administrators), which copies all package metadata — including protected file references, role-based access restrictions, and password lock settings — into an attacker-owned clone that they can then edit to remove restrictions and download the previously protected files.
