Apollo Mcp Server
Monthly
Apollo MCP Server versions prior to 1.7.0 fail to validate HTTP Host headers on StreamableHTTP transport, allowing unauthenticated remote attackers with user interaction to bypass same-origin policy via DNS rebinding attacks and invoke GraphQL tools or access resources on behalf of a local user. The vulnerability is limited to HTTP-based deployments without network-level controls and does not affect stdio transport configurations. Vendor-released patch: version 1.7.0.
