CVE-2026-43577Network attack vector

Authenticated file read via interaction-driven navigation bypass

Published May 6, 2026 · Updated May 6, 2026

File read in OpenClaw before 2026.4.9 allows remote authenticated users to read local files through browser act/evaluate routes. These routes fail to re-check the page URL after interaction-driven main-frame navigation, permitting a pivot to the local CDP origin and disallowed file:// pages. Valid Gateway access is required, and exposure is limited to files readable by the OpenClaw process.
