Summary
OpenClaw: Browser snapshot and screenshot routes could expose internal page content after navigation
Details

Summary

Browser snapshot and screenshot routes could expose internal page content after navigation.

Affected Packages / Versions

  • Package: openclaw
  • Ecosystem: npm
  • Affected versions: < 2026.4.14
  • Patched versions: >= 2026.4.14

Impact

Authenticated browser tool callers could use snapshot, screenshot, or tab routes that did not consistently validate the final browser target after route-driven navigation. In restrictive browser SSRF configurations this could expose content from internal or otherwise disallowed pages.

Technical Details

The fix re-checks browser snapshot, screenshot, and tab route results against the configured browser SSRF policy before returning page content. Regression coverage was added around snapshot/screenshot and tab-route flows.

Fix

The issue was fixed in #66040. The first stable tag containing the fix is v2026.4.14, and openclaw@2026.4.14 includes the fix.

Fix Commit(s)

  • b75ad800a59009fc47eaa3471410f69046150e59
  • PR: #66040

Release Process Note

Users should upgrade to openclaw 2026.4.14 or newer. The latest npm release, 2026.4.14, already includes the fix.
