Kerentanan Concurrent Execution using Shared Resource with Improper Synchronization ('Race Condition'). Skor CVSS 3.0 8.2 (High) menurut hackerone.com.
An attacker can make the Node.js HTTP/2 server completely unavailable by sending a small amount of HTTP/2 frames packets with a few HTTP/2 frames inside. It is possible to leave some data in nghttp2 memory after reset when headers with HTTP/2 CONTINUATION frame are sent to the server and then a TCP connection is abruptly closed by the client triggering the Http2Session destructor while header frames are still being processed (and stored in memory) causing a race condition.
