OpenClaw: Browser snapshot and screenshot routes could expose internal page content after navigation
Packages
Details
As written in the advisory (Markdown source, shown as plain text).
## 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 `[email protected]` 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.
