Io.netty:netty codec http: Netty SPDY SETTINGS frame count materializes unbounded settings map (CVE-2026-55831)CVE-2026-55831 0 Netty's SPDY SETTINGS decoder in the io.netty:netty-codec-http library accepts a peer-declared SETTINGS entry count up to the 24-bit frame-length limit without limiting the number of unique setting IDs materialized. A remote unauthenticated SPDY/3.1 peer can send a single large SETTINGS frame that creates an unbounded number of map entries, causing significant heap growth and CPU usage. This leads to a resource exhaustion denial of service. The vulnerability affects the DefaultSpdySettingsFrame class which uses a TreeMap to store settings without a count cap.
