CVE-2026-41300Network attack vector

Credential disclosure via persisted declined endpoint

Published Apr 20, 2026 · Updated Apr 20, 2026

Credential disclosure in OpenClaw before 2026.3.31 allows remote attackers to receive gateway credentials through remote onboarding. In promptRemoteGatewayConfig, declining a discovered WebSocket endpoint leaves suggestedUrl unchanged, so the manual Gateway WebSocket URL prompt remains prefilled with the attacker-supplied address. Exploitation requires an operator to accept that prefilled address; the client then sends gateway credentials to the malicious endpoint, with no reported integrity or availability impact.
