Official Description

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.

Technical Analysis

CVE-2026-42426 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.8.
