Summary

The All In One Login WordPress plugin lets unauthenticated attackers take over any account, including administrator accounts, by brute-forcing the short numeric code used by its default-enabled passwordless email login. The plugin does not limit the number of attempts or count failed attempts toward its own brute-force protection.

Read the original 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.
