CVE-2026-56452

Path traversal in the sshd-scp component of Apache MINA SSHD. Apache MINA SSHD is a Java library for client-side and server-side SSH.

The implementation of receiving files or directories via SCP did not validate filenames in SCP "C" or "D" commands. A malicious sender could send filenames containing paths, resulting in files to be written in attacker-controlled places.

The issue affects only

• applications that use no longer supported Apache MINA SSHD versions < 2.0.0 and use the SCP functions to receive files,
• or applications using sshd-scp in Apache MINA SSHD >= 2.0.0 to receive files.

Applications using Apache MINA SSHD >= 2.0.0 not using sshd-scp are not affected.

The issue is fixed in Apache MINA 2.19.0 and 3.0.0-M5. Affected applications are advised to upgrade to these versions.

These are all security issues fixed in the apache-sshd-2.19.0-2.1 package on the GA media of openSUSE Tumbleweed.

This update for apache-sshd fixes the following issues:

Update to upstream version 2.19.0.

Security issues fixed:

• CVE-2026-56452: remote users can use SCP to send filenames that lead to arbitrary file writes due to a path traversal issue in the sshd-scp component of Apache MINA SSHD. (bsc#1272158).
• CVE-2026-56623: remote users can obtain access to git repositories outside of the configured server-side root directory on Windows systems due to path traversal issue in org.apache.sshd:sshd-git (bsc#1271993).
• CVE-2026-56624: users can authenticate with certificates containing the force-command option but still execute other commands due to improper validation of certificate options in Apache MINA SSHD (bsc#1271992).
• CVE-2026-58624: remote execution of JGit commands can lead to arbitrary file writes due to improper input validation in sshd-git of Apache MINA SSHD (bsc#1271991).
