CVE-2026-1536

Full vulnerability record from the local CVENow database.

Description

A flaw was found in libsoup. An attacker who can control the input for the Content-Disposition header can inject CRLF (Carriage Return Line Feed) sequences into the header value. These sequences are then interpreted verbatim when the HTTP request or response is constructed, allowing arbitrary HTTP headers to be injected. This vulnerability can lead to HTTP header injection or HTTP response splitting without requiring authentication or user interaction.

Un atacante que puede controlar la entrada para el encabezado Content-Disposition puede inyectar secuencias CRLF (retorno de carro y salto de línea) en el valor del encabezado. Estas secuencias se interpretan luego literalmente cuando se construye la solicitud o respuesta HTTP, permitiendo la inyección de encabezados HTTP arbitrarios. Esta vulnerabilidad puede conducir a la inyección de encabezados HTTP o a la división de respuesta HTTP sin requerir autenticación ni interacción del usuario."
