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

Status: published. Published: 2026-11-05. Updated: 2026-11-05.

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.
