OpenClaw: Browser SSRF hostname validation could be bypassed by DNS rebinding
Summary
Browser SSRF hostname validation could be bypassed by DNS rebinding.
Affected Packages / Versions
- Package:
openclaw - Ecosystem: npm
- Affected versions:
< 2026.4.10 - Patched versions:
>= 2026.4.10
Impact
Browser navigation policy could validate a hostname/IP resolution that differed from the address Chromium ultimately used, allowing DNS rebinding style SSRF pivots.
Technical Details
The fix tightens strict browser hostname navigation so unallowlisted hostname URLs fail closed under restrictive policy.
Fix
The issue was fixed in #64367. The first stable tag containing the fix is v2026.4.10, and openclaw@2026.4.14 includes the fix.

Release Process Note
Users should upgrade to openclaw 2026.4.10 or newer. The latest npm release, 2026.4.14, already includes the fix.
