OpenSSH 9.2p1 adds a new EnableEscapeCommandline
apt-listchanges: News
openssh (1:9.2p1-1) unstable; urgency=medium
OpenSSH 9.2 includes a number of changes that may affect existing configurations:
ssh(1): add a new EnableEscapeCommandline ssh_config(5) option that controls whether the client-side ~C escape sequence that provides a command-line is available. Among other things, the ~C command-line could be used to add additional port-forwards at runtime.
This option defaults to "no", disabling the ~C command-line that was previously enabled by default. Turning off the command-line allows platforms that support sandboxing of the ssh(1) client (currently only OpenBSD) to use a stricter default sandbox policy.
