Attackers can supply an externally valid URL that passes validation and returns an HTTP redirect to an internal or restricted resource, allowing the browser to follow the redirect and fetch the final destination without revalidation, thereby gaining access to internal network services and sensitive endpoints.\u00a0This issue is distinct from CVE-2024-56800, which describes redirect-based SSRF generally. This vulnerability specifically arises from a post-redirect enforcement gap in implemented SSRF protections, where validation is applied only to the initial request and not to the final redirected destination."}, {"lang": "es", "value": "La versi\u00f3n 2.8.0 de Firecrawl y anteriores contienen una vulnerabilidad de omisi\u00f3n de protecci\u00f3n de falsificaci\u00f3n de petici\u00f3n del lado del servidor (SSRF) en el servicio de scraping de Playwright donde la validaci\u00f3n de la pol\u00edtica de red se aplica solo a la URL inicial proporcionada por el usuario y no a los destinos de redirecci\u00f3n subsiguientes. Los atacantes pueden proporcionar una URL externamente v\u00e1lida que pasa la validaci\u00f3n y devuelve una redirecci\u00f3n HTTP a un recurso interno o restringido, permitiendo que el navegador siga la redirecci\u00f3n y obtenga el destino final sin revalidaci\u00f3n, obteniendo as\u00ed acceso a servicios de red internos y puntos finales sensibles. Este problema es distinto de CVE-2024-56800, que describe la SSRF basada en redirecci\u00f3n de forma general. Esta vulnerabilidad surge espec\u00edficamente de una brecha de aplicaci\u00f3n posterior a la redirecci\u00f3n en las protecciones SSRF implementadas, donde la validaci\u00f3n se aplica solo a la petici\u00f3n inicial y no al destino final redirigido."}], "lastModified": "2026-07-14T19:16:58.107", "sourceIdentifier": "disclosure@vulncheck.com"}
