Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process.

In ssh in OpenSSH before 10.6, a $ or \ character can occur in a command-line username, leading to injection.
