Risk and Exploitability

The CVSS score of 8.7 denotes a high severity. EPSS is not available, making the precise exploitation probability unclear. The vulnerability is not listed in the CISA KEV catalog.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade OpenClaw to version 2026.8.1 or later to apply the authorization logic fix.
  • If an immediate upgrade is not possible, restrict access to the skill tool dispatch endpoint so that only owners can invoke it, via configuration settings or firewall rules.
  • Conduct a review of the system to ensure no unauthorized skill command endpoints remain exposed and that permission checks for owner‑only tools are enforced.
