【中文导读】UltimateAI 存在认证绕过风险（严重风险）。具体受影响版本、触发条件和修复方案以 NVD/厂商公告为准。 【原始描述】The UltimateAI plugin for WordPress is vulnerable to authentication bypass in versions up to, and including, 2.8.3. This is due to insufficient verification on the user being supplied in the 'ultimate_ai_register_or_login_with_google' function. This makes it possible for unauthenticated attackers to log in as any existing user on the site, such as an administrator, if they have access to the email.
