Title

OpenClaw < 2026.4.2 - Information Disclosure via Gateway Connect Snapshot

Summary

OpenClaw before 2026.4.2 exposes configPath and stateDir metadata in Gateway connect success snapshots to non-admin authenticated clients. Non-admin clients can recover host-specific filesystem paths and deployment details, enabling host fingerprinting and facilitating chained attacks.

Severity

GHSA-2F7J-RP58-MR42

Vulnerability from github – Published: 2026-04-07 18:15 – Updated: 2026-05-06 23:24

Summary

OpenClaw: Gateway hello snapshots exposed host config and state paths to non-admin clients

Details

Summary

Before OpenClaw 2026.4.2, the Gateway connect success snapshot exposed local configPath and stateDir metadata to non-admin clients. Low-privilege authenticated clients could learn host filesystem layout and deployment details that were not needed for their role.

Impact

A non-admin client could recover host-specific filesystem paths and related deployment metadata, aiding host fingerprinting and chained attacks. This was an information-disclosure issue, not a direct authorization bypass.

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: <= 2026.4.1
Patched versions: >= 2026.4.2
Latest published npm version: 2026.4.1

Fix Commit(s)

676b748056b5efca6f1255708e9dd9469edf5e2e — limit connect snapshot metadata to admin-scoped clients

Release Process Note

The fix is present on main and is staged for OpenClaw 2026.4.2. Publish this advisory after the 2026.4.2 npm release is live.

Thanks @topsec-bunney for reporting.
