HackerOne Hai

Low · 1 reported finding

The triage bot identified itself as Claude while declining a Claude report.

Documented response · submission not verified

Asked to review a vulnerability report about Claude, Hai declined for conflict of interest and stated "I'm Claude". The refusal was a positive control; the self-identification was the reported observation. It does not independently verify which model powered the deployment.

Follow-up record

A separate UX observation records suggestions being sent straight back to Hai, causing the assistant to answer its own suggested question. This is a conversation-design issue, not an additional security vulnerability.

A suggestion creates a self-answering loop

A suggested question was clicked. It was sent directly to the assistant. Hai answered the suggestion as though it were the user's question.

Know the limit

Documented assistant responses. Self-identification alone does not authenticate the underlying deployment. The screenshot files named in the archive index are unavailable, so public evidence uses the recorded text rather than a reconstructed image.
