Hi, The following vulnerability was published for netty. CVE-2026-33871[0]: | 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 `CONTINUATION` frames, | combined with a bypass of existing size-based mitigations using | zero-byte frames, allows an user to cause excessive CPU consumption | with minimal bandwidth, rendering the server unresponsive. Versions | 4.1.132.Final and 4.2.10.Final fix the issue. If you fix the vulnerability please also make sure to include the CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
