Credential disclosure via auto-approved jq environment access

Published Jul 28, 2026 · Updated Jul 28, 2026

Information disclosure in Next Level Builders GoClaw 3.13.0 through 3.13.2 allows remote authenticated users to read gateway secrets via jq. ExecTool.Execute auto-approves jq as a safe binary, while its host child inherits GOCLAW_GATEWAY_TOKEN because the credential scrub list omits it. Exploitation requires operator-level API access, full security with on-miss approval, jq on the host, and the gateway token in the process environment.
