CVE-2025-58057 PoC or lab evidence Netty's BrotliDecoder is vulnerable to DoS via zip bomb style attack Netty is an asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In netty-codec-compression versions 4.1.124.Final and below, and netty-codec versions 4.2.4.Final and below, when supplied with specially crafted input, BrotliDecoder and certain other decompression decoders will allocate a large number of reachable byte buffers, which	6.9 · CVSS 4.0 · MediumSource: CNA	No confirmation recordedNo CISA KEV match was present at the last successful refresh.

CVE-2026-33871 Scheduled assessment Netty HTTP/2 CONTINUATION Frame Flood DoS via Zero-Byte Frame Bypass 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 c	8.7 · CVSS 4.0 · HighSource: CNA	No confirmation recordedNo CISA KEV match was present at the last successful refresh.
