CVE-2026-1539
Full vulnerability record from the local CVENow database.
Description
A flaw was found in the libsoup HTTP library that can cause proxy authentication credentials to be sent to unintended destinations. When handling HTTP redirects, libsoup removes the Authorization header but does not remove the Proxy-Authorization header if the request is redirected to a different host. As a result, sensitive proxy credentials may be leaked to third-party servers. Applications using libsoup for HTTP communication may unintentionally expose proxy authentication data.

"value": "Se encontró una falla en la librería HTTP libsoup que puede causar que las credenciales de autenticación de proxy se envíen a destinos no deseados. Al manejar redirecciones HTTP, libsoup elimina el encabezado Authorization pero no elimina el encabezado Proxy-Authorization si la solicitud es redirigida a un host diferente. Como resultado, las credenciales de proxy sensibles pueden filtrarse a servidores de terceros. Las aplicaciones que usan libsoup para comunicación HTTP pueden exponer involuntariamente datos de autenticación de proxy."
