CVE-2025-64102

Zitadel is open-source identity infrastructure software. Prior to 4.6.0, 3.4.3, and 2.71.18, an attacker can perform an online brute-force attack on OTP, TOTP, and passwords. While Zitadel allows preventing online brute force attacks in scenarios like TOTP, Email OTP, or passwords using a lockout mechanism. The mechanism is not enabled by default and can cause a denial of service for the corresponding user if enabled. Additionally, the mitigation strategies were not fully implemented in the more recent resource-based APIs. This vulnerability is fixed in 4.6.0, 3.4.3, and 2.71.18.

Summary		(es) Zitadel es un software de infraestructura de identidad de código abierto. Antes de las versiones 4.6.0, 3.4.3 y 2.71.18, un atacante puede realizar un ataque de fuerza bruta en línea en OTP, TOTP y contraseñas. Aunque Zitadel permite prevenir ataques de fuerza bruta en línea en escenarios como TOTP, OTP por correo electrónico o contraseñas utilizando un mecanismo de bloqueo. El mecanismo no está habilitado por defecto y puede causar una denegación de servicio para el usuario correspondiente si se habilita. Además, las estrategias de mitigación no estaban completamente implementadas en las API más recientes basadas en recursos. Esta vulnerabilidad está corregida en las versiones 4.6.0, 3.4.3 y 2.71.18.
