Description

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.

[email protected] is published on npm and the compiled package contains the fix.
Focused regression coverage for this path passed before publication.
