CVE-2026-56452

7.5 · HIGH

Path traversal in the sshd-scp component of Apache MINA SSHD.

Published Jul 20, 2026CWE-22EPSS 0.77%

Overview

CVE-2026-56452 is a high-severity vulnerability. It was published on July 20, 2026 and has a CVSS 3.1 base score of 7.5 (HIGH).

This vulnerability has a CVSS 3.1 base score of 7.5, rated HIGH. It can be exploited remotely over the network. No authentication or special privileges are required for exploitation.

Technical description

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.

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.
