CVE-2026-7010

HTTP::Tiny versions before 0.093 for Perl do not validate CRLF in HTTP request lines or control field header values. The unvalidated inputs are the method and URI in the request line, the URL host that becomes the `Host:` header, and HTTP/1.1 control data field values. An attacker who controls one of these inputs, for example a user supplied URL passed to a webhook or URL fetch endpoint, can inject additional headers and smuggle requests to the upstream server.

Summary		(es) Las versiones de HTTP::Tiny anteriores a la 0.093 para Perl no validan CRLF en las líneas de solicitud HTTP o los valores de encabezado de campos de control. Las entradas no validadas son el método y la URI en la línea de solicitud, el host de la URL que se convierte en el encabezado ’Host:’, y los valores de los campos de datos de control de HTTP/1.1. Un atacante que controla una de estas entradas, por ejemplo, una URL proporcionada por el usuario y pasada a un webhook o a un punto final de recuperación de URL, puede inyectar encabezados adicionales y contrabandear solicitudes al servidor ascendente.
