NVD description
OpenClaw before 2026.3.31 misclassifies proxied remote requests as loopback connections in the diffs viewer when allowRemoteViewer is disabled, allowing unauthorized access. Attackers can bypass access controls by sending proxied requests that are incorrectly identified as local loopback traffic, circumventing intended remote viewer restrictions.
What to do
- Upgrade OpenClaw to
2026.3.31or later. - Do not expose the component's API or UI to the internet without authentication in front of it.
