CVE-2026-58624 is a medium-severity flaw (CVSS 5.4) affecting mina sshd. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

Improper input validation in sshd-git in Apache MINA SSHD. Apache MINA SSHD is a Java library for client-side and server-side SSH. Component org.apache.sshd:sshd-git provides though its GitPgmCommandFactory a way to configure an Apache MINA SSHD server such that SSH clients can remotely execute git commands via the JGit library on git repositories stored on the server. This GitPgmCommandFactory allowed a user authenticated via SSH to run

apache mina sshd UPGRADE

Affected: >= 2.0.0 and < 2.19.0 · 3.0.0 m1 · 3.0.0 m2 · 3.0.0 m3 · 3.0.0 m4

Fixed in: 2.19.0

Safe to downgrade to: a release before 2.0.0

1. Check installed version

apt-cache policy mina-sshd || rpm -q mina-sshd || mina-sshd --version

2. UPGRADE to 2.19.0 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade mina-sshd

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade mina-sshd

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 2.0.0 (Debian / Ubuntu)

apt-cache madison mina-sshd sudo apt install mina-sshd=<VERSION_BEFORE_2.0.0> sudo apt-mark hold mina-sshd

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list mina-sshd sudo dnf downgrade mina-sshd-<VERSION_BEFORE_2.0.0> sudo dnf versionlock add mina-sshd

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
