CVE-2026-19256— All In One Login 2.4.0 - 2.4.1 - Unauthenticated Account Takeover via Email OTP Brute Force

Quick assessment

Affected

Unknown All In One Login

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.

在 2.5.0 版本之前的 All In One Login WordPress 插件，未对默认启用的无密码邮箱登录功能所使用的短数字代码的尝试次数进行充分限制，也未将这些失败尝试纳入其自身的暴力破解防护机制。这使得未认证的攻击者能够接管任何账户，包括管理员账户。

Vulnerability Title

All In One Login 2.4.0 - 2.4.1 - Unauthenticated Account Takeover via Email OTP Brute Force

Source: CVE Program / CVE List V5

Vulnerability Description

The All In One Login WordPress plugin before 2.5.0 does not adequately restrict the number of attempts that can be made against the short numeric code used by its default-enabled passwordless email login, and does not feed those failed attempts into its own brute-force protection, allowing unauthenticated attackers to take over any account including administrators.
