Description
The Media Library Assistant plugin for WordPress is vulnerable to unauthorized access of data in all versions up to, and including, 3.43, due to a missing capability check and nonce check on the mla_fill_compat_fields_action() Media Modal AJAX handler. The handler loads any post ID supplied in the request and returns its term assignments for the plugin-supported taxonomies. This makes it possible for authenticated attackers with subscriber-level access and above to read the taxonomy terms assigned to posts and attachments they are not permitted to edit, including private and draft content.
