## Summary Browser SSRF policy default allowed private-network navigation. ## Affected Packages / Versions - Package: `openclaw` - Ecosystem: npm - Affected versions: `< 2026.4.14` - Patched versions: `>= 2026.4.14` ## Impact Browser SSRF protection could allow private-network navigation by default in paths where restrictive behavior was expected, exposing internal services or metadata endpoints through browser-driven requests. ## Technical Details The fix preserves strict SSRF configuration semantics, keeps private-network access disabled unless explicitly opted in, and updates loopback CDP readiness handling for the stricter default. ## Fix The issue was fixed in #66354 and #66386. The first stable tag containing the fix is `v2026.4.14`, and `openclaw@2026.4.14` includes the fix. ## Fix Commit(s) - `024f4614a1a1831406e763adc40ef226e3d5e9ed` - `1dabfef28db523e7de81edeb3dd689e9171236a2` - `213c36cf51121ef6c05cfccd78037371f968f31a` - `7eecfa411df3d12e6b810e6ca5df47254fc3db3f` - PR: #66354, #66386 ## Release Process Note Users should upgrade to `openclaw` 2026.4.14 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.
