CVE-2026-7505Public exploitNetwork attack vector

Unauthenticated RPC access via fail-open authorization

Published Apr 30, 2026 · Updated Apr 30, 2026

Improper authorization in Next Level Builders GoClaw and GoClaw Lite 3.8.0 through 3.8.5 allows remote attackers to invoke protected RPCs. The gateway treats invalid or absent credentials as an authenticated viewer, while its default-permit RBAC assigns unclassified methods viewer access. This chain exposes live logs and heartbeat writes without credentials; command execution follows only when an agent's exec tool is enabled.
