CVE-2026-40885

Full vulnerability record from the local CVENow database.

Description

goshs is a SimpleHTTPServer written in Go. From 2.0.0-beta.4 to 2.0.0-beta.5, goshs leaks file-based ACL credentials through its public collaborator feed when the server is deployed without global basic auth. Requests to .goshs-protected folders are logged before authorization is enforced, and the collaborator websocket broadcasts raw request headers, including Authorization. An unauthenticated observer can capture a victim's folder-specific basic-auth header and replay it to read, upload, overwrite, and delete files inside the protected subtree. This vulnerability is fixed in 2.0.0-beta.6.

Desde la 2.0.0-beta.4 hasta la 2.0.0-beta.5, goshs filtra credenciales ACL basadas en archivos a través de su feed público de colaboradores cuando el servidor es desplegado sin autenticación básica global. Las solicitudes a carpetas protegidas por .goshs son registradas antes de que se aplique la autorización, y el websocket del colaborador transmite encabezados de solicitud sin procesar, incluyendo Authorization. Un observador no autenticado puede capturar el encabezado de autenticación básica específico de la carpeta de una víctima y reproducirlo para leer, cargar, sobrescribir y eliminar archivos dentro del subárbol protegido. Esta vulnerabilidad está corregida en la 2.0.0-beta.6."
