CVE Severity Published▾ Status Exploitation Description
CVE-2023-44487 High 2023-10-10 Mitigation candidate Exploited The HTTP/2 protocol allows a denial of service (server resource consumption) because request cancellation can reset many streams quickly, as exploited in the wild in August through October 2023.
CVE-2022-2048 High 2022-07-07 No exploit published No public exploit In Eclipse Jetty HTTP/2 server implementation, when encountering an invalid HTTP/2 request, the error handling has a bug that can wind up not properly cleaning up the active connections and associated resources. This can lead to a Denial of Service scenario where there are no enough resources left to process good requests.
