## C-Kermit: RCE vulnerabilities
Severity: unknown. Patch status: fix status unknown.
Affected: C-Kermit

Multiple vulnerabilities in C-Kermit can lead to RCE when working with a malicious peer.

## Steps
1. Search the repo, its CI and infra config for C-Kermit. If present, report the version in use and whether it's affected.
2. No source names a fix yet; check the vendor advisory. Until one ships: restrict network access to it.

## Report
A table: file, product or package, version in use, affected yes/no, exact fix. Then anything a human has to check outside the repo.

If you have the pwned.coffee MCP server (https://pwned.coffee/mcp), call lookup_cve for the latest, and check_repo with this repo's lockfiles, Dockerfiles and workflows for a full receipt.
