Vulnerability in openclaw (CVE-2026-45003)

Summary

Vulnerability in openclaw (CVE-2026-45003). Confidential information can be exposed externally. Mitigation: upgrade to 2026.4.22 or later.

Original description

The description as published by the source.

Summary

Workspace dotenv files cannot override connector endpoint hosts.

Affected Packages / Versions

  • Package: openclaw (npm)
  • Affected versions: <= 2026.4.21
  • Fixed version: 2026.4.22

Impact

A workspace .env file could set connector endpoint variables for Matrix, Mattermost, IRC, or Synology-related connectors and redirect runtime traffic away from the operator-configured endpoint.

Fix

Workspace .env loading now blocks those endpoint variables, including per-account Matrix homeserver suffixes and generic base-url/API-host style overrides. Trusted global runtime dotenv loading remains separate.
