CVE-2026-56623: CWE-22 Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in Apache Software Foundation Apache MINA SSHD
CVE-2026-56623 is a path traversal vulnerability in the Apache MINA SSHD sshd-git component affecting Windows systems. It allows an authenticated remote user to access git repositories outside the configured server-side root directory due to ineffective path validation on Windows. This impacts applications using sshd-git on Windows. The issue is fixed in Apache MINA SSHD 2.19.0 and 3.0.0-M5.
AI Analysis
Technical Summary
This vulnerability involves improper limitation of a pathname to a restricted directory (CWE-22) in the Apache MINA SSHD sshd-git component on Windows. The path validation implemented for a prior vulnerability (CVE-2026-48827) was partly ineffective on Windows, allowing authenticated remote users to traverse directories outside the intended root directory of the git server. Only applications using sshd-git on Windows are affected. The vulnerability is resolved by upgrading to Apache MINA SSHD 2.19.0 or 3.0.0-M5.
Potential Impact
An authenticated remote user on a Windows system running a git server implemented with Apache MINA SSHD sshd-git can access git repositories outside the configured root directory. This can lead to unauthorized access to sensitive repository data. The confidentiality impact is high, integrity impact is low, and availability is not affected.
Mitigation Recommendations
Users should upgrade affected applications to Apache MINA SSHD version 2.19.0 or later, or 3.0.0-M5 or later for the 3.x pre-release line. This upgrade addresses the path traversal issue on Windows. Patch status is not explicitly stated but the vendor advisory clearly recommends upgrading to these versions to fix the issue.
