What the vulnerability does

01Description

OpenClaw before 2026.4.8 contains an improper authorization vulnerability where the node.pair.approve method accepts operator.write scope instead of the narrower operator.pairing scope, allowing unprivileged users to approve node pairing. Attackers with operator.write permissions can bypass pairing approval restrictions to gain unauthorized access to exec-capable nodes.
