Loading vulnerability…
nghttp2 versions prior to 1.61.0 continue accepting and decoding an unbounded number of HTTP/2 CONTINUATION frames after a stream has been reset, in order to preserve synchronization of the HPACK compression context. An attacker can exploit this behavior to force excessive HPACK decoding work. Version 1.61.0 limits the number of CONTINUATION frames accepted per stream.
