  "title": "HTTP response desynchronization in Starman",
  "summary": "Starman versions before 0.4019 can emit response content for HEAD and other bodyless HTTP responses, causing persistent connections to become misaligned. An attacker may cause a front-end proxy that reuses upstream connections to associate responses with the wrong requests. The issue requires keep-alive or pipelined connections and an affected response path.",
  "mitigation": "Upgrade Starman to version 0.4019 or later. Until upgraded, reduce exposure by disabling or limiting reuse of persistent upstream connections through front-end proxies.",
