CVE-2026-41403 PUBLISHED

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

Assigner: VulnCheck
Reserved: 20.04.2026 Published: 28.04.2026 Updated: 28.04.2026

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.
