CVE-2026-77771— miniOrange 2FA (Free & Pro) - 2FA Bypass via Session-Scoped OTP Lockout

Quick assessment

Affected
Unknown miniOrange 2FA
Exploitation
No confirmed in-the-wild exploitation; assess based on exposure
Recommended action
Check the vendor advisory and references for a fixed version. If immediate upgrade is impossible, restrict exposure and increase monitoring.

miniOrange 2FA WordPress 插件在 6.3.1 之前的版本以及 19.3 之前的版本存在一个缺陷：该插件未将第二因子验证的尝试次数限制与正在受攻击的账户关联，而是将其绑定到由客户端提供且可随时更改的标识符上。这使得已经知道受害者密码的攻击者能够进行无限制的一次性密码（OTP）猜测，从而绕过第二因子认证。此外，第二个验证端点完全没有设置尝试次数限制。
