Description
The BetterDocs plugin for WordPress is vulnerable to unauthorized modification of data via the update_docs_term and update_docs_order_by_category AJAX actions in all versions up to, and including, 4.9.5 due to a missing per-post capability check. Both handlers only checked the edit_docs capability, which contributors and authors have. This makes it possible for authenticated attackers, with contributor-level access and above, to move other users' docs between categories and to overwrite a category's saved doc order, which can hide published docs from the category listing.
