  "title": "Inbound stream timeout denial of service in libp2p-messaging",
  "summary": "libp2p-messaging can retain inbound stream tasks without enforcing its configured receive timeout, allowing connections to remain active beyond expected cleanup. A peer that can establish a P2P connection may consume handler capacity and memory and disrupt messaging for its connection.",
  "mitigation": "Configure strict total, per-peer, and per-source connection limits, and restrict messaging access to trusted peers where feasible. Apply an upstream patch or release that enforces per-stream read and write timeouts when available; no fixed version is recorded.",
