 "title": "Nexter Blocks <= 5.0.7 - Authenticated (Subscriber+) Missing Authorization to Backend Cache Deletion",
 "description": "The Nexter Blocks plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the tpgb_backend_clear_cache AJAX action in all versions up to, and including, 5.0.7. The action is protected only by a nonce that is printed on front-end pages. This makes it possible for authenticated attackers, with subscriber-level access and above, to delete the plugin's generated backend CSS/JS cache files.",
