OpenClaw: Workspace dotenv files cannot override connector endpoint hosts
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.
Fix Commit(s)

Verification
- The fix commit is contained in the public v2026.4.22 tag.
- [email protected] is published on npm and the compiled package contains the fix.
- Focused regression coverage for this path passed before publication.
