Rules

What the policy asks of you, and the bug types it won't reward, quoted from Usable Machines, Inc. (dba Kindo)'s policy. "We" in these lines means the program, not this site.

While testing

  • You must include proof of the exploit.
  • Do not exploit the vulnerability beyond what is necessary to demonstrate its existence.
  • we ask that you disclose it to us privately, allowing us to resolve it before it is made public
  • Do not report vulnerabilities through social media or other public forums.
  • Please submit reports only to the address on the policy page ; reports sent elsewhere may not be reviewed.
  • Keep all communication confidential.

Not accepted

  • purely informational issues or low‑impact findings (for example, clickjacking on pages with no sensitive actions)
  • Reports of missing headers, best-practice gaps, or theoretical risks without a working exploit
  • Speculative vulnerabilities that aren’t exploitable
  • Duplicate or known issues
  • Prompt injection, jailbreak attempts, and other LLM-specific attack techniques against Deep Hat
