PT-2026-92421

Ember's HTTP/2 stack replenishes the inbound flow-control window based on bytes received off the wire, not bytes consumed by the application. Received DATA is buffered in an unbounded per-stream channel. Flow control therefore provides no backpressure: a peer can stream a large or unbounded body...

JLSEC-2026-4 nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C

nghttp2 is an implementation of the Hypertext Transfer Protocol version 2 in C. The nghttp2 library prior to version 1.61.0 keeps reading the unbounded number of HTTP/2 CONTINUATION frames even after a stream is reset to keep HPACK context in sync. This causes excessive CPU usage to decode HPACK...

nghttp2: CONTINUATION frames DoS

A vulnerability was found in how nghttp2 implements the HTTP/2 protocol. There are insufficient limitations placed on the amount of CONTINUATION frames that can be sent within a single stream. This issue could allow an unauthenticated remote attacker to send packets to vulnerable servers, which...
