CVE-2026-43973
Description
A flaw was found in gun. A malicious server can exploit this uncontrolled resource consumption vulnerability by sending a partial HTTP/1.1 response that never completes. This causes the client's memory buffer to grow without bounds, leading to unbounded heap growth and potentially exhausting all available memory on the node, resulting in a Denial of Service (DoS) crash.
