The Forgotten Bug: How a Node.js Core Design Flaw Enables HTTP Request Splitting
AI-collected research leads through 22 September 2026, including targeted additions between broader sweeps. Unranked, incomplete, not community-vetted, and subject to change.
Surveys callbacks and events that permit a Node.js request path to change after constructor validation but before header serialization. Library comparisons and a decoded Express proxy route show how unsafe application assignments can introduce request splitting, with the request lifecycle identifying where validation must actually occur.
