What is CVE-2026-35620?
CVE-2026-35620 is a medium-severity missing authorization vulnerability in Openclaw Openclaw, published on 10 Apr 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
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.
Weakness: CWE-862
