      "value": "Path traversal on Windows in Apache MINA SSHD component sshd-git. Apache MINA SSHD is a Java library for client-side and server-side SSH.\n\n\n\n\nA git server implemented with Apache MINA SSHD component sshd-git and running on Windows could allow an authenticated remote user access to git repositories outside of the configured server-side root directory. The path validation applied for CVE-2026-48827 in Apache MINA SSHD 2.18.0 and 3.0.0-M4 was partly ineffective for Servers running on Windows.\n\n\n\n\nApplications are affected if they use org.apache.sshd:sshd-git to implement a git server and run on Windows. Applications not using sshd-git or not running on Windows are not affected.\n\n\n\n\nUsers are advised to upgrade affected applications to Apache MINA SSHD 2.19.0, which fixes the issue.\n\n\n\n\nThe issue also is present in the pre-release milestones 3.0.0-M1 to 3.0.0-M4 for a new upcoming new major version 3.0.0. Again, applications are affected only if they use sshd-git and run on Windows. Upgrade affected applications to 3.0.0-M5."

      "value": "Salto de ruta en Windows en el componente sshd-git de Apache MINA SSHD. Apache MINA SSHD es una biblioteca Java para SSH del lado del cliente y del lado del servidor.\n\nUn servidor git implementado con el componente sshd-git de Apache MINA SSHD y ejecutándose en Windows podría permitir a un usuario remoto autenticado acceder a repositorios git fuera del directorio raíz del lado del servidor configurado. La validación de ruta aplicada para CVE-2026-48827 en Apache MINA SSHD 2.18.0 y 3.0.0-M4 fue parcialmente ineficaz para servidores ejecutándose en Windows.\n\nLas aplicaciones se ven afectadas si utilizan org.apache.sshd:sshd-git para implementar un servidor git y se ejecutan en Windows. Las aplicaciones que no utilizan sshd-git o que no se ejecutan en Windows no se ven afectadas.\n\nSe aconseja a los usuarios actualizar las aplicaciones afectadas a Apache MINA SSHD 2.19.0, que corrige el problema.\n\nEl problema también está presente en los hitos de prelanzamiento 3.0.0-M1 a 3.0.0-M4 para una nueva versión principal próxima 3.0.0. De nuevo, las aplicaciones se ven afectadas solo si utilizan sshd-git y se ejecutan en Windows. Actualice las aplicaciones afectadas a 3.0.0-M5."
