DescriptionOpenClaw before 2026.3.28 contains a privilege escalation vulnerability in chat.send that allows write-scoped gateway callers to trigger admin-only session reset operations. Attackers can rotate target sessions, archive prior transcript state, and force new session IDs without requiring admin scope by exploiting improper authorization checks in the chat.send path.
