- Alias
- GHSA-2v4p-qf9q-27wj
Description
In google.golang.org/grpc, servers configured with xDS routing can panic when processing requests that lack both :authority and Host headers. The HTTP/2 transport layer accepted requests missing these headers, and the xDS server routing interceptor attempted to index the empty authority slice, causing an unhandled panic and terminating the server.
