  * 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
