CANopen-Bench is a bench/lab tool. It binds to 127.0.0.1 by default
and has no authentication — anyone who can reach the port can
control the connected CAN bus. Do not expose it to untrusted networks;
if you must bind to 0.0.0.0 (e.g. in Docker), put it behind your own
access control.
Please report vulnerabilities privately instead of opening a public issue: use Report a vulnerability under this repository's Security tab, which opens an advisory only you and the maintainer can see. If you would rather not go through GitHub, unsix.de lists a way to get in touch.
Include steps to reproduce and, if possible, an assessment of impact. You will get a response within a few days; a fix or an agreed disclosure plan follows as soon as realistic.
Only the latest release receives security fixes.
