Summary
A path traversal vulnerability in Apache MINA SSHD bundle sshd-git. Lack of path validation in git operations allows authenticated SSH users to access git repositories outside the configured git server root directory.
Risk Assessment
The organization risks unauthorized access to git repositories, potentially leading to source code and sensitive data leakage.
Recommendation
Update Apache MINA SSHD to version 2.18.0 (or 3.0.0-M4 for version 3.0.0) and implement additional access controls for repositories.
Other vulnerabilities in Apache MINA SSHD
See all- CVE-2022-45047Critical
The class org.apache.sshd.server.keyprovider.SimpleGeneratorHostKeyProvider in Apache MINA SSHD versions up to 2.9.1 uses Java deserialization to load a serialized java.security.PrivateKey. It is one of several implementations that can be used for loading the host keys of an SSH server.
- CVE-2026-58624Medium
Vulnerability in Apache MINA SSHD (sshd-git component) allows an authenticated SSH user to execute arbitrary JGit commands, including writing files to arbitrary locations via `git archive --output`.
- CVE-2026-56624High
Improper certificate validation in Apache MINA SSHD (server-side). The server did not check for force-command or verify-required options in OpenSSH certificates, allowing an authenticated user to execute other commands than specified. Fixed in versions 2.19.0 and 3.0.0-M5.
- CVE-2026-56623High
A path traversal vulnerability in the sshd-git component of Apache MINA SSHD on Windows allows an authenticated remote user to access git repositories outside the configured server root directory. The fix for CVE-2026-48827 was partially ineffective on Windows.
- CVE-2026-56452High
Path traversal vulnerability in the sshd-scp component of Apache MINA SSHD. A malicious sender can send filenames containing paths, allowing files to be written to arbitrary locations. Affects applications using SCP to receive files.
Original NVD description (English source)
Path traversal vulnerability in Apache MINA SSHD bundle sshd-git. Lack of path validation in git-upload-pack, git-receive-pack, and other git operations allows users authenticated over SSH access to git repositories outside the configured git server root directory. Applications are affected if they use org.apache.sshd:sshd-git. Applications not using sshd-git are not affected. Users are advised to upgrade affected applications to Apche MINA SSHD 2.18.0, which fixes the issue. The issue also is present in the pre-release milestones 3.0.0-M1 to 3.0.0-M3 for a new upcoming new major version 3.0.0. Again, applications are affected only if they use sshd-git. Upgrade affected applications to 3.0.0-M4. We would like to point out that a professional git server should not rely solely on file system layout and permissions, but should implement additional security controls to govern access to git repositories and operations allowed on particular git repositories.
