CVSS 3.0
8.2 highCVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:HCVE-2024-27983
High (8.2). EPSS 87% chance of exploitation in the next 30 days.
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.
