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