CVE-2026-56624

Name of the Vulnerable Software and Affected Versions Apache MINA SSHD versions prior to 2.19.0 Apache MINA SSHD versions prior to 3.0.0-M5

Description Improper certificate validation occurs during server-side OpenSSH user authentication. The server fails to check or validate the force-command or verify-required options embedded in certificates. This allows a user to authenticate with a certificate containing a force-command option and potentially execute commands other than the one specified, depending on the server implementation.

Recommendations Upgrade to version 2.19.0. Upgrade to version 3.0.0-M5.
