CVE-2026-42431Network attack vector

Authenticated profile mutation via proxy guard bypass

Published Apr 28, 2026 · Updated Apr 28, 2026

Incorrect authorization in OpenClaw before 2026.4.8 allows remote authenticated users to modify persistent browser profiles via node.invoke. The node.invoke(browser.proxy) path forwards persistent profile-mutation requests without applying the browser.request guard that blocks those operations. An approved paired desktop node exposing browser.proxy and low-privilege Gateway access are required; successful requests alter persistent browser configuration without a reported availability impact.
