Name of the Vulnerable Software and Affected Versions OpenClaw versions prior to 2026.3.31

Description When allowRemoteViewer is disabled, the diffs viewer misclassifies proxied remote requests as loopback connections. This allows attackers to bypass access controls by sending proxied requests that are incorrectly identified as local loopback traffic, granting unauthorized access by circumventing remote viewer restrictions.

Recommendations Update to version 2026.3.31.
