HIGHgrpc 1.51.0-1.52.4 - Reachable Assertion via Malformed HTTP/2 Headers
Title source: llmDescription
There exists an vulnerability causing an abort() to be called in gRPC. The following headers cause gRPC's C++ implementation to abort() when called via http2: te: x (x != trailers) :scheme: x (x != http, https) grpclb_client_stats: x (x == anything) On top of sending one of those headers, a later header must be sent that gets the total header size past 8KB.
