The Dokan Pro plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 4.0.5. This is due to the plugin not properly validating a user's identity prior to updating their password during a staff password reset. This makes it possible for authenticated attackers, with vendor-level access and above, to elevate their privilege to the level of a staff member and then change arbitrary user passwords, including those of administrators in order to gain access to their accounts. By default, the plugin allows customers to become vendors.

The Dokan Pro plugin for WordPress is vulnerable to privilege escalation via updatecapabilities REST Endpoint in all versions up to, and including, 5.0.4. This is due to the updatecapabilities() REST handler accepting arbitrary capability strings from the request body and passing them directly to WPUser::addcap() 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 vendorstaff account, leading to a full site takeover.
