| CVE-2023-39325 | Hig | 0.49 | 7.5 | 0.04 | Oct 11, 2023 | A malicious HTTP/2 client which rapidly creates requests and immediately resets them can cause excessive server resource consumption. While the total number of requests is bounded by the http2.Server.MaxConcurrentStreams setting, resetting an in-progress request allows the… | ||
