Netty is an asynchronous, event-driven network application framework. In versions prior to 4.1.132.Final and 4.2.10.Final, a remote user can trigger a Denial of Service DoS against a Netty HTTP/2 server by sending a flood of CONTINUATION frames. The server's lack of a limit on the number of...

CVE-2026-33871

CVE-2026-33871 affects Netty, an asynchronous event-driven network framework. The issue occurs when a remote attacker floods an HTTP/2 server with CONTINUATION frames, exploiting an unlimited frame-count and bypassing size-based mitigations with zero-byte frames. This can cause high CPU usage and...
