      "value": "A vulnerability in zenml-io/zenml versions 0.57.0 through 0.94.2 allows an attacker to bypass rate-limiting on the `POST /api/v1/login` and self password-change endpoints by rotating the `X-Forwarded-For` header. The rate limiter keys requests by `request.client.host`, which is derived from the `X-Forwarded-For` header when Uvicorn is launched with `--proxy-headers --forwarded-allow-ips *`. This configuration allows clients to control the value of `request.client.host`, effectively bypassing rate-limiting protections. This vulnerability leaves the affected endpoints open to unthrottled credential guessing attacks."

      "value": "Una vulnerabilidad en las versiones 0.57.0 a 0.94.2 de zenml-io/zenml permite a un atacante eludir la limitación de velocidad en los endpoints ’POST /api/v1/login’ y de cambio de contraseña propio rotando el encabezado ’X-Forwarded-For’. El limitador de velocidad clavea las solicitudes por ’request.client.host’, que se deriva del encabezado ’X-Forwarded-For’ cuando Uvicorn se inicia con ’--proxy-headers --forwarded-allow-ips *’. Esta configuración permite a los clientes controlar el valor de ’request.client.host’, eludiendo eficazmente las protecciones de limitación de velocidad. Esta vulnerabilidad deja los endpoints afectados expuestos a ataques de adivinanza de credenciales sin limitación."
