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

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