CVE-2026-41403
OpenClaw < 2026.3.31 - Access Control Bypass via Proxied Remote Request Misclassification
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.
