Detailsinfo

The manipulation with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-862. The product does not perform an authorization check when an actor attempts to access a resource or perform an action. This is going to have an impact on integrity, and availability. CVE summarizes:

OpenClaw before 2026.3.24 contains missing authorization vulnerabilities in the /send and /allowlist chat command handlers. The /send command allows non-owner command-authorized senders to change owner-only session delivery policy settings, and the /allowlist mutating commands fail to enforce operator.admin scope. Attackers with operator.write scope can invoke /send on|off|inherit to persistently mutate the current session's sendPolicy, and execute /allowlist add commands to modify config-backed allowFrom entries and pairing-store allowlist entries without proper admin authorization.
