The Themify Builder plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 7.7.7. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with subscriber-level access and above, to overwrite or delete the generated CSS stylesheet file of arbitrary posts, including private and draft posts owned by other users, and modify plugin-scoped font options. The required CSRF nonce (tf_nonce) is emitted on public front-end builder pages via wp_localize_script, making it trivially obtainable by any authenticated user visiting such a page.
