CVE-2026-41299

HIGH

7.1

Description

OpenClaw before 2026.3.28 contains an authorization bypass vulnerability in the chat.send gateway method where ACP-only provenance fields are gated by self-declared client metadata from WebSocket handshake rather than verified authorization state. Authenticated operator clients can spoof ACP identity labels and inject reserved provenance fields intended only for the ACP bridge by manipulating client metadata during connection.
