Title

OpenClaw < 2026.4.8 - Improper Authorization in node.pair.approve via operator.write Scope

Summary

OpenClaw before 2026.4.8 contains an improper authorization vulnerability where the node.pair.approve method accepts operator.write scope instead of the narrower operator.pairing scope, allowing unprivileged users to approve node pairing. Attackers with operator.write permissions can bypass pairing approval restrictions to gain unauthorized access to exec-capable nodes.

BREW-OPENCLAW-CLI-CVE-20… (GHSA-67MF-F936-PPXF)

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

Summary

OpenClaw `node.pair.approve` placed in `operator.write` scope instead of `operator.pairing` allows unprivileged pairing approval

Details

Impact

OpenClaw node.pair.approve placed in operator.write scope instead of operator.pairing allows unprivileged pairing approval.

The pairing approval method accepted operator.write instead of the narrower pairing scope and admin requirement for exec-capable nodes.

OpenClaw is a user-controlled local assistant. This advisory is scoped to the OpenClaw trust model and does not assume a multi-tenant service boundary.

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: <= v2026.04.01
Patched versions: 2026.4.8

Fix

The issue was fixed on main and is available in the patched npm version listed above. The verified fixed tree is commit d7c3210cd6f5fdfdc1beff4c9541673e814354d5.

Verification

The fix was re-checked against main before publication, including targeted regression tests for the affected security boundary.

GHSA-67MF-F936-PPXF

Vulnerability from github – Published: 2026-04-09 17:36 – Updated: 2026-05-06 02:41

Summary

OpenClaw `node.pair.approve` placed in `operator.write` scope instead of `operator.pairing` allows unprivileged pairing approval

Details

Impact

OpenClaw node.pair.approve placed in operator.write scope instead of operator.pairing allows unprivileged pairing approval.

The pairing approval method accepted operator.write instead of the narrower pairing scope and admin requirement for exec-capable nodes.

OpenClaw is a user-controlled local assistant. This advisory is scoped to the OpenClaw trust model and does not assume a multi-tenant service boundary.

Affected Packages / Versions

Package: openclaw (npm)
Affected versions: <= v2026.04.01
Patched versions: 2026.4.8

Fix

The issue was fixed on main and is available in the patched npm version listed above. The verified fixed tree is commit d7c3210cd6f5fdfdc1beff4c9541673e814354d5.

Verification

The fix was re-checked against main before publication, including targeted regression tests for the affected security boundary.

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.
