CyberRota Analysis
This is a high severity vulnerability with a CVSS score of 8.8. It affects WordPress. Exploitation may require the attacker to be authenticated.
Original NVD Description
The Dokan Pro plugin for WordPress is vulnerable to privilege escalation via update_capabilities REST Endpoint in all versions up to, and including, 5.0.4. This is due to the `update_capabilities()` REST handler accepting arbitrary capability strings from the request body and passing them directly to WP_User::add_cap() with no allowlist validation, only verifying that the caller holds the dokandar capability. This makes it possible for authenticated attackers with a self-provisioned Vendor-level access and above, on sites with the Vendor Staff module enabled, to grant arbitrary WordPress capabilities, including administrator, to any vendor_staff account, leading to a full site takeover.
