 "title": "Admin and Site Enhancements (ASE) <= 9.1.4 - Unauthenticated Denial of Service via 'asenha_password_protection' Cookie",
 "description": "The Admin and Site Enhancements (ASE) plugin for WordPress is vulnerable to Denial of Service via the 'asenha_password_protection' cookie in versions 5.8.0 up to, and including, 9.1.4. This is due to the Password Protection module passing the raw, visitor-supplied cookie value to wp_check_password() as the stored hash, which lets the visitor choose the hashing algorithm and its cost factor. This makes it possible for unauthenticated attackers to send a bcrypt string with a very high cost factor in the cookie, so that each request keeps a PHP worker busy until the PHP execution time limit ends it, and a small number of requests can make the site unavailable. Exploitation requires the Password Protection module, which is off by default, to be enabled.",
