Internal response disclosure via unvalidated tool URL
Published Jul 14, 2026 · Updated Jul 14, 2026
SSRF in MasterGo Magic MCP 0.1 and 0.2.0 allows attackers to read server-reachable responses via a crafted tool URL. The mcp__getComponentLink handler accepts url as an unconstrained string, sends it directly in an HTTP GET, and returns the response body as text. Access to an MCP client or prompt-injected agent that can invoke the tool is required, exposing internal services and cloud metadata reachable from the host.
