  3. CVE-2025-48938
go-gh is a collection of Go modules to make authoring GitHub CLI extensions easier. A security vulnerability has been identified in versions prior to 2.12.1 where an attacker-controlled GitHub Enterprise Server could result in executing arbitrary commands on a user's machine by replacing HTTP URLs provided by GitHub with local file paths for browsing. In `2.12.1`, `Browser.Browse()` has been enhanced to allow and disallow a variety of scenarios to avoid opening or executing files on the filesystem without unduly impacting HTTP URLs. No known workarounds are available other than upgrading.

Summary
  • (es) go-gh es una colección de módulos de Go que facilita la creación de extensiones de la CLI de GitHub. Se identificó una vulnerabilidad de seguridad en versiones anteriores a la 2.12.1, donde un servidor de GitHub Enterprise controlado por un atacante podía ejecutar comandos arbitrarios en el equipo de un usuario al reemplazar las URL HTTP proporcionadas por GitHub con rutas de archivos locales para la navegación. En la versión 2.12.1, se mejoró `Browser.Browse()` para permitir y deshabilitar diversos escenarios y evitar la apertura o ejecución de archivos en el sistema de archivos sin afectar negativamente a las URL HTTP. No se conocen workarounds aparte de la actualización.
