is, therefore, affected by a command injection vulnerability:

  - Vulnerabilities in the Git node allowed authenticated users with permission to create or modify workflows to
    execute arbitrary system commands or read arbitrary files on the n8n host. (CVE-2026-25053)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
