The vendor acknowledged the issue but provides additional context for the CVSS rating: "a11y-mcp is a local stdio MCP server - it has no HTTP endpoint and is not network-accessible. The caller is always the local user or an LLM acting on their behalf with user approval."

    Recommended action: Upgrade to 1.0.5 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
