01How to report a vulnerability

Please email security@isg.green and include:

  • A clear description of the issue
  • Steps to reproduce, where applicable
  • Any proof-of-concept — keep it minimal, do not exfiltrate data
  • Your preferred name for acknowledgement, or a note if you would like to remain anonymous

We will acknowledge your report within 5 business days and provide status updates as we investigate.
