 "title": "Clean Login <= 1.111 - Unauthenticated Authentication Bypass via Reusable Password Restore Link",
 "description": "The Clean Login plugin for WordPress is vulnerable to Authentication Bypass via the password restore link in all versions up to, and including, 1.111, due to a weak password recovery mechanism. The restore link was protected only by a WordPress nonce whose action was the bare user ID and which was created for a logged-out visitor, instead of a single-use password reset key. The link was not invalidated after use and stayed valid for 12-24 hours, and opening it logged the visitor in as the target user. This makes it possible for unauthenticated attackers who obtain a leaked or previously used restore link to log in as that user, including administrators, and take over the account.",
