OpenClaw before 2026.8.1 Authentication Bypass via Session Reset
OpenClaw (npm package openclaw) versions >= 2026.5.2 and < 2026.8.1 contain an incorrect authorization vulnerability in WhatsApp group handling. A group sender who is admitted for ordinary messages but denied by commands.allowFrom or owner command authorization can issue the /new command to reset the shared group session and persist a provider and model override. This allows a command-denied group member to select a provider and model already permitted by the operator for subsequent turns in the shared group session, potentially changing provider routing, cost, data flow, or availability. It does not allow adding a new provider or host command execution. The issue is fixed in version 2026.8.1.
