CVE-2026-41372
|
| Summary | OpenClaw: Trailing-dot localhost CDP hosts could bypass remote loopback protections ## Summary Before OpenClaw 2026.4.2, remote CDP discovery could return a trailing-dot localhost host such as `localhost.` and bypass OpenClaw's loopback-host normalization. That let a non-loopback remote CDP profile pivot the follow-up connection back onto localhost. ## Impact A hostile discovery response could retarget authenticated browser control toward a localhost-resolving endpoint on the OpenClaw host. This weakened the existing remote-CDP loopback protection and could expose localhost-backed browser state. ## Affected Packages / Versions - Package: `openclaw` (npm) - Affected versions: `<= 2026.4.1` - Patched versions: `>= 2026.4.2` - Latest published npm version: `2026.4.1` ## Fix Commit(s) - `9c22d636697336a6b22b0ae24798d8b8325d7828` — normalize localhost absolute-form CDP hosts before loopback checks ## Release Process Note The fix is present on `main` and is staged for OpenClaw `2026.4.2`. Publish this advisory after the `2026.4.2` npm release is live. Thanks @smaeljaish771 for reporting. |
