Original description
The description as published by the source.
OpenClaw before 2026.4.21 contains an authorization bypass vulnerability in command-auth.ts that allows non-owner senders to execute owner-enforced slash commands when wildcard inbound senders are configured without explicit owner allowFrom settings. Attackers can exploit this by sending commands like /send, /config, or /debug on affected channels to bypass owner-only command authorization checks.
