CVE-2026-5440

Summary

A memory exhaustion vulnerability exists in the HTTP server due to unbounded use of the Content-Length header. The server allocates memory directly based on the attacker supplied header value without enforcing an upper limit. A crafted HTTP request containing an extremely large Content-Length value can trigger excessive memory allocation and server termination, even without sending a request body.
