CVE-ID: CVE-2026-56623

CWE-ID: CWE-22

Exploitation vector: Remote access

Exploit availability: No public exploit available

The vulnerability allows a remote user to access git repositories outside of the configured server-side root directory.

The vulnerability exists due to path traversal in org.apache.sshd:sshd-git when handling repository path access on Windows. A remote user can supply crafted repository paths to access git repositories outside of the configured server-side root directory.

Only applications that use sshd-git to implement a git server and run on Windows are vulnerable.
