openclawnpmDescription
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.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for openclaw, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update openclaw to 2026.4.22 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-55cf-xx38-4p9p is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-55cf-xx38-4p9p can be triaged on real exposure rather than presence alone.
Tailored to GHSA-55cf-xx38-4p9p. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-55cf-xx38-4p9p in your dependencies?
O3 Security finds GHSA-55cf-xx38-4p9p across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
