【中文导读】Keyy Two Factor Authentication (like Clef) 存在权限提升风险（高危风险）。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 Keyy Two Factor Authentication (like Clef) plugin for WordPress is vulnerable to privilege escalation via account takeover in all versions up to, and including, 1.2.3. This is due to the plugin not properly validating a user's identity associated with a token generated. This makes it possible for authenticated attackers, with subscriber-level access and above, to generate valid auth tokens and leverage that to auto-login as other accounts, including administrators, as long as the administrator has the 2FA set up.
