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.
