CVE-2026-56623

7.1 · HIGH

Path traversal on Windows in Apache MINA SSHD component sshd-git.

Published Jul 20, 2026CWE-22EPSS 0.87%

Overview

CVE-2026-56623 is a high-severity vulnerability. It was published on July 20, 2026 and has a CVSS 3.1 base score of 7.1 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.1, rated HIGH. It can be exploited remotely over the network. Some level of privileges is required for exploitation.

Technical description

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.

A 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.

Applications 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.

Users are advised to upgrade affected applications to Apache MINA SSHD 2.19.0, which fixes the issue.

The 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. Upgrad

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
