      "value": "Swarms through 6.8.1, fixed in commit 8b0fc9e, contains a server-side request forgery vulnerability in the _is_safe_url function that fails to validate hostnames through DNS resolution, allowing attackers to bypass the blocklist. Attackers can supply user-controlled image or audio URLs that resolve to private, loopback, or metadata addresses to reach internal services and exfiltrate credentials."

      "value": "Swarms a través de 6.8.1, corregido en el commit 8b0fc9e, contiene una vulnerabilidad de falsificación de petición del lado del servidor en la función _is_safe_url que no valida los nombres de host a través de la resolución DNS, permitiendo a los atacantes eludir la lista de bloqueo. Los atacantes pueden proporcionar URLs de imagen o audio controladas por el usuario que se resuelven en direcciones privadas, de bucle invertido o de metadatos para alcanzar servicios internos y exfiltrar credenciales."
