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.

How do I mitigate CVE-2026-42433 if there is no patch (or I can't update yet)?

Put an independent control in front of the weakness: restrict the affected endpoint or interface to trusted networks, require an additional authentication factor or proxy-level check, and invalidate existing sessions and credentials in case the flaw has already been used.

Description

Summary

Matrix profile config persistence was reachable from operator.write message tools.

Affected Packages / Versions

Package: openclaw
Ecosystem: npm
Affected versions: < 2026.4.10
Patched versions: >= 2026.4.10

Impact

Gateway operator.write message-tool paths could reach Matrix profile persistence that should have required admin-level authority.

Technical Details

The fix gates Matrix profile updates for non-owner message-tool runs and prevents write-scoped callers from mutating persistent profile config.

Fix

The issue was fixed in #62662. The first stable tag containing the fix is v2026.4.10, and [email protected] includes the fix.
