CVE-2025-57814

request-filtering-agent is an http(s).Agent implementation that blocks requests to Private/Reserved IP addresses. Versions 1.x.x and earlier contain a vulnerability where HTTPS requests to 127.0.0.1 bypass IP address filtering, while HTTP requests are correctly blocked. This allows attackers to potentially access internal HTTPS services running on localhost, bypassing the library's SSRF protection. The vulnerability is particularly dangerous when the application accepts user-controlled URLs and internal services are only protected by network-level restrictions. This vulnerability has been fixed in request-filtering-agent version 2.0.0. Users should upgrade to version 2.0.0 or later.

Summary		(es) request-filtering-agent es una implementación de http(s).Agent que bloquea las solicitudes a direcciones IP privadas/reservadas. Las versiones 1.xx y anteriores contienen una vulnerabilidad donde las solicitudes HTTPS a 127.0.0.1 eluden el filtrado de direcciones IP, mientras que las solicitudes HTTP se bloquean correctamente. Esto permite a los atacantes acceder potencialmente a servicios HTTPS internos que se ejecutan en el host local, evadiendo la protección SSRF de la librería. Esta vulnerabilidad es especialmente peligrosa cuando la aplicación acepta URL controladas por el usuario y los servicios internos solo están protegidos por restricciones a nivel de red. Esta vulnerabilidad se ha corregido en la versión 2.0.0 de request-filtering-agent. Los usuarios deben actualizar a la versión 2.0.0 o posterior.
