Please report security issues privately, not in a public issue. Use GitHub's private vulnerability reporting: open the repository's Security tab and choose Report a vulnerability. Include what you found, how to reproduce it, and the gpubridge and PyTorch versions.
If that option isn't available, open an issue that asks for a private contact and leave out the details.
gpubridge is an alpha, and only the latest release and main get fixes. It
assumes every rank of a job is trusted: like torch.distributed, its process
groups and bridge transports don't authenticate peers or encrypt traffic. Run
jobs on networks you trust.
