Prior to ToolHive CLI 0.30.1 and ToolHive Studio 0.38.0, locally run MCP server containers use the default network permission profile without network isolation, permitting access to host.docker.internal while ToolHive API and MCP proxy endpoints are reachable without authentication. A malicious or compromised MCP server can use the Docker gateway to contact host-local services, other ToolHive-managed MCP proxies, or the ToolHive control plane without escaping the container. This access can expose data and logs, invoke sibling MCP tools, alter process or workload state, and disrupt services. ToolHive Studio additionally sends network_isolation as false and overrides the backend's secure isolation default. This issue is fixed in ToolHive CLI 0.30.1 and ToolHive Studio 0.38.0.","state":0,"publishedAt":null,"modifiedAt":null,"affected":[],"metrics":[{"system":"EUVD CVSS 3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H","score":8.8,"severity":null}],"references":["https://github.com/stacklok/toolhive/security/advisories/GHSA-qg2g-g9w3-m5h8","https://github.com/stacklok/toolhive-studio/pull/2469","https://github.com/stacklok/toolhive/pull/5583","https://github.com/stacklok/toolhive-studio/commit/968182d7f3ee1e55123369e66ad88f82128119b0","https://github.com/stacklok/toolhive/commit/d8f40cb1599b8bf66657f2dfff15bfbfc236e712","https://github.com/stacklok/toolhive-studio/releases/tag/v0.38.0","https://github.com/stacklok/toolhive/releases/tag/v0.30.1"],"sourceUrl":"https://euvd.enisa.europa.eu/vulnerability/EUVD-2026-83167","license":"ENISA EUVD · source terms and attribution apply","enrichment":{"sourceStatus":null,"weaknesses":[],"productCriteria":[],"sourceDates":{"datePublished":"Sep 18, 2026, 4:34:55 PM","dateUpdated":"Sep 18, 2026, 4:51:27 PM"},"relatedAdvisories":[],"note":"EUVD source date text has no stated timezone and is retained without inventing a UTC instant.
