Prior to 2.1.7, isPublicHttpUrl / assertPublicHttpUrl in src/utils/urlSafety.ts do not recognize bracketed IPv6 literals and do not resolve DNS, which combine to allow non-blind SSRF with the response body returned to the caller. This vulnerability is fixed in 2.1.7."

Antes de la versión 2.1.7, isPublicHttpUrl / assertPublicHttpUrl en src/utils/urlSafety.ts no reconocen los literales IPv6 entre corchetes y no resuelven DNS, lo que en conjunto permite un SSRF no ciego con el cuerpo de la respuesta devuelto al llamador. Esta vulnerabilidad se corrige en la versión 2.1.7."
