CVE-2026-43582

| Summary | 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. ## Fix Commit(s) - `121c452d666d4749744dc2089287d0227aae2ed3` - PR: #64367 ## Release Process Note Users should upgrade to `openclaw` 2026.4.10 or newer. The latest npm release, `2026.4.14`, already includes the fix. ## Credits Thanks to @zsxsoft, with sponsorship from @KeenSecurityLab and @qclawer for reporting this issue. |
