Executive Summary

CVE-2026-42422 is a role bypass vulnerability in the OpenClaw package versions before 2026.4.8. It occurs in the device.token.rotate function, which improperly allows minting tokens for roles that have not been approved through the intended device role-upgrade pairing process.

This flaw lets attackers bypass the authorization mechanism designed to control role upgrades, enabling them to create or maintain roles and scopes without the necessary approval.

The vulnerability corresponds to CWE-863 (Incorrect Authorization), meaning the product performs authorization checks but fails to do so correctly, allowing unauthorized access or actions.

Impact Analysis

This vulnerability can have a high impact because it allows attackers to bypass role upgrade controls and mint tokens for unapproved roles.

As a result, attackers can preserve or create roles and scopes without intended approval, potentially gaining unauthorized access or privileges within the OpenClaw environment.

The CVSS v4.0 base score of 7.7 and v3.1 base score of 8.8 reflect high severity, indicating significant impacts on confidentiality, integrity, and availability.

Mitigation Strategies

To mitigate the CVE-2026-42422 vulnerability, you should upgrade the OpenClaw package to version 2026.4.8 or later, where the issue in the device.token.rotate function has been fixed.

This update ensures that the authorization checks for role upgrades are properly enforced, preventing unauthorized minting of tokens for unapproved roles.

Compliance Impact

The provided information does not specify how CVE-2026-42422 affects compliance with common standards and regulations such as GDPR or HIPAA.
