CVE-2023-29193

SpiceDB is an open source, Google Zanzibar-inspired, database system for creating and managing security-critical application permissions. The spicedb serve command contains a flag named --grpc-preshared-key which is used to protect the gRPC API from being accessed by unauthorized requests. The values of this flag are to be considered sensitive, secret data. The /debug/pprof/cmdline endpoint served by the metrics service (defaulting running on port 9090) reveals the command-line flags provided for debugging purposes. If a password is set via the --grpc-preshared-key then the key is revealed by this endpoint along with any other flags provided to the SpiceDB binary. This issue has been fixed in version 1.19.1.
