Vulnerability from osv_homebrew – Published: 2026-08-13 17:21 – Updated: 2026-11-13 09:11 – Source website

Summary

OpenClaw: Android accepted cleartext remote gateway endpoints and sent stored credentials over ws://

Details

Summary

Before OpenClaw 2026.4.2, Android accepted non-loopback cleartext ws:// gateway endpoints and would send stored gateway credentials over that connection. Discovery beacons or setup codes could therefore steer the client onto a cleartext remote endpoint.

Impact

A user who followed a forged discovery result or scanned a crafted setup code could disclose stored gateway credentials to an attacker-controlled endpoint in plaintext. This was a transport-security bug in the Android gateway client.

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)

a941a4fef9bc43b2973c92d0dcff5b8a426210c5 — require TLS for remote Android gateway endpoints

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 @zsxsoft for reporting.

How durations are calculated

Following the VTEM framework (Black Hat USA 2015), time to patch starts when the vendor or a coordinator was informed, total time to patch at discovery, and disclosure to patch at public disclosure; vendor response time runs from the report to its acknowledgement. Time to exploit and time unpatched start at the earliest discovery or report, falling back to public disclosure. Unpatched time ends at the first recorded patch, or the calculation time when no patch is recorded. Exploitation to patch shows the interval between those two events; a published proof of concept is a public exploit, not exploitation.

Each result shows its source dates. A negative interval means the end event came first; when date-only inputs leave the order open, the result says so. Date-only inputs are approximate. The earliest evidence wins: KEV report dates and sightings are labelled as such. Records describing another vulnerability are listed but never calculated from, and a PoC alone does not establish exploitation. Missing patch evidence does not prove that no patch exists. Filters below change the event list only.
