CVE-2026-41339Network attack vector

Host path disclosure via ungated connection snapshot

Published Apr 23, 2026 · Updated Apr 23, 2026

Information disclosure in OpenClaw Gateway before 2026.4.2 allows remote authenticated users to read host filesystem paths. The buildGatewaySnapshot function added configPath, stateDir, and authMode to every hello-ok snapshot without checking for the operator.admin scope. A valid low-privilege Gateway credential and operator.read scope are sufficient; the disclosed layout supports host fingerprinting but does not bypass authorization.
