id	cvss score	package	impact	workaround	epss_score	kev
CVE-2025-9784	7.5	io.undertow:undertow-core-2.3.18.Final			0.00224	false
CVE-2025-55163	8.2	io.netty:netty-codec-http2-4.1.118.Final	Although this vulnerability is legit, it is relatively hard to exploit this vulnerability to cause actual server instability, because modern hardware will not spend much resources to handle bogus RSTSTREAM frames.	A user can attach an Http2FrameListener implementation that disconnects a client that sends too many RSTSTREAM or any other invalid frames in a certain amount of time.	0.00081	false
CVE-2025-58057	6.9	io.netty:netty-codec-4.1.118.Final	An attacker can easily leverage this vulnerability to cause errors OOME, etc by sending a request that contains the malicious data compressed with Brotli compression algorithm. This is basically similar to the wellknown zipbomb attack.		0.00033	false
CVE-2025-58056	8.2	io.netty:netty-codec-http-4.1.118.Final	An attacker can smuggle a potentially malicious request to the victim by sending a malformed HTTP chunks. It may have a high impact depending on whether you have a reverse proxy that performs strict validation or not.		0.00026	false
