OpenClaw < 2026.3.31 - Access Control Bypass via Proxied Remote Request Misclassification

State: Published
Severity: 6.3 Medium
Published: Apr 28, 2026
Updated: Apr 29, 2026
Reserved: Apr 20, 2026

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.
