CVE-2026-1467
Full vulnerability record from the local CVENow database.
Description
A flaw was found in libsoup, an HTTP client library. This vulnerability, known as CRLF (Carriage Return Line Feed) Injection, occurs when an HTTP proxy is configured and the library improperly handles URL-decoded input used to create the Host header. A remote attacker can exploit this by providing a specially crafted URL containing CRLF sequences, allowing them to inject additional HTTP headers or complete HTTP request bodies. This can lead to unintended or unauthorized HTTP requests being forwarded by the proxy, potentially impacting downstream services.

"value": "Se encontró una falla en libsoup, una biblioteca cliente HTTP. Esta vulnerabilidad, conocida como inyección CRLF (Carriage Return Line Feed), ocurre cuando se configura un proxy HTTP y la biblioteca maneja incorrectamente la entrada decodificada de URL utilizada para crear el encabezado Host. Un atacante remoto puede explotar esto al proporcionar una URL especialmente diseñada que contiene secuencias CRLF, permitiéndoles inyectar encabezados HTTP adicionales o cuerpos completos de solicitudes HTTP. Esto puede llevar a que solicitudes HTTP no intencionadas o no autorizadas sean reenviadas por el proxy, afectando potencialmente a los servicios posteriores."
