Description
Heym before v0.0.112 contains a token leakage vulnerability in build_public_base_url() that allows unauthenticated attackers to redirect HITL review links by spoofing Origin or X-Forwarded-Host headers. Attackers can trigger anonymous workflows with forged headers so reviewer notifications point to attacker domains, capturing capability tokens to submit decisions executed with owner credentials.
