Error Log

When gRPC HTTP2 stack raised a header size exceeded error it skipped parsing the rest of the HPACK frame. This caused any HPACK table mutations to also be skipped resulting in a desynchronization of HPACK tables between sender and receiver. If leveraged say between a proxy and a backend this could lead to requests from the proxy being interpreted as containing headers from different proxy clients - leading to an information leak that can be used for privilege escalation or data exfiltration. We recommend upgrading beyond the commit contained in  https://github.com/grpc/grpc/pull/32309
