OpenClaw before 2026.3.23 contains an authentication bypass vulnerability in the Canvas gateway where authorizeCanvasRequest() unconditionally allows local-direct requests without validating bearer tokens or canvas capabilities. Attackers can send unauthenticated loopback HTTP and WebSocket requests to Canvas routes to bypass authentication and gain unauthorized access.

OpenClaw versions 2026.3.11 through 2026.3.24 contain a session isolation bypass vulnerability where session_status resolves sessionId to canonical session keys before enforcing visibility checks. Sandboxed child sessions can exploit this to access parent or sibling sessions that should be blocked by explicit sessionKey restrictions.

OpenClaw before 2026.3.25 contains a server-side request forgery vulnerability in multiple channel extensions that fail to properly guard configured base URLs against SSRF attacks. Attackers can exploit unprotected fetch() calls against configured endpoints to rebind requests to blocked internal destinations and access restricted resources.

OpenClaw before 2026.3.23 contains a replay identity vulnerability in Plivo V2 signature verification that allows attackers to bypass replay protection by modifying query parameters. The verification path derives replay keys from the full URL including query strings instead of the canonicalized base URL, enabling attackers to mint new verified request keys through unsigned query-only changes to signed requests.

OpenClaw before 2026.3.25 contains a privilege escalation vulnerability where silent local shared-auth reconnects auto-approve scope-upgrade requests, widening paired device permissions from operator.read to operator.admin. Attackers can exploit this by triggering local reconnection to silently escalate privileges and achieve remote code execution on the node.

OpenClaw before 2026.3.25 contains an improper access control vulnerability in the HTTP /sessions/:sessionKey/kill route that allows any bearer-authenticated user to invoke admin-level session termination functions without proper scope validation. Attackers can exploit this by sending authenticated requests to kill arbitrary subagent sessions via the killSubagentRunAdmin function, bypassing ownership and operator scope restrictions.
