Connection Termination

grpc is vulnerable to Connection Termination. An attacker can terminate the connection between a HTTP2 proxy and the gRPC server by providing a -bin suffixed headers, which leads to a base64 encoding error, causing an application crash...

Connection Confusion

grpc is vulnerable to Connection Confusion. The vulnerability exists when the gRPC HTTP2 stack raised a header size exceeded error, and it skipped parsing the rest of the HPACK frame, which caused any HPACK table mutations also to be skipped, resulting in the desynchronization of HPACK tables...

GHSA-9HXF-PPJV-W6RQ gRPC connection termination issue

gRPC contains a vulnerability whereby a client can cause a termination of connection between a HTTP2 proxy and a gRPC server: a base64 encoding error for -bin suffixed headers will result in a disconnection by the gRPC server, but is typically allowed by HTTP2 proxies. We recommend upgrading beyo...
