attestedinferred

The A–E grade is our heuristic synthesis — a "review this" prompt, not a verdict. Each factor is tagged by what backs it: attested (a verifiable record), reported (a third party's claim), or inferred (our own heuristic, e.g. permissions). See methodology.

HIGH
MCP Python SDK vulnerability in the FastMCP Server causes validation error, leading to DoS via mcp · 1 hop CVE-2025-53366 fixed in 1.9.4
HIGH
Model Context Protocol (MCP) Python SDK does not enable DNS rebinding protection by default via mcp · 1 hop CVE-2025-66416 fixed in 1.23.0
HIGH
MCP Python SDK has Unhandled Exception in Streamable HTTP Transport, Leading to Denial of Service via mcp · 1 hop CVE-2025-53365 fixed in 1.10.0
tool safety all quiet

No tool-safety findings — heuristic detectors run on the compute-risk cadence; a finding appears when a tool trips a rule.

Heuristic, inferred signals — false positives (legitimately powerful tools, forks, language ports) are expected. Treat each as "review this", not a verdict. See the ecosystem-wide picture on the security hub, or the fleet security of be.nvy.
