CVE-2026-93995: Apache MINA SSHD: Remote execution of JGit "archive -o=file.zip" can write file on the server
Improper input validation in sshd-git in Apache MINA SSHD, versions up to 2.19.0 and 3.0.0-M1 to 3.0.0-M5. Apache MINA SSHD is a Java library for client-side and server-side SSH.
Component org.apache.sshd:sshd-git provides though class GitPgmCommandFactory a way to configure an Apache MINA SSHD server such that authenticated SSH clients can remotely execute git commands via the JGit library on git repositories stored on the server. In CVE-2026-58624 this mechanism was restricted to only a few git commands, including "git archive" without "--output" or "-o" options such that the resulting archive would not be written on the server but instead sent back to the client over the SSH connection.
The fix done for CVE-2026-58624 was insufficient as it missed removing the single-argument "-o=file.zip" version of the command parameter from the "archive" command.
Users are recommended to upgrade to version 2.20.0 or 3.0.0-M6, which fix this issue.

Frequently Asked Questions
Which deployments are exposed?
Deployments using the org.apache.sshd:sshd-git component with GitPgmCommandFactory configured to allow authenticated SSH clients to run JGit commands against repositories stored on the server are exposed. The issue affects versions up to 2.19.0 and versions 3.0.0-M1 through 3.0.0-M5.
What does an attacker need to exploit this issue?
An attacker needs valid SSH authentication and access to the configured remote Git command functionality. They can exploit the archive command's single-argument -o=file.zip option to cause an archive to be written on the server.
Is upgrading the recommended remediation?
Yes. Upgrade to Apache MINA SSHD version 2.20.0 or 3.0.0-M6, which fix the issue.
