@grpc/grpc-js: The server transmits some error messages thrown by method handlers to the client in status messages

CVSS 3.7 EPSS <1%Fix available

[ Description ]Official description

@grpc/grpc-js implements the core functionality of gRPC purely in JavaScript, without a C++ addon. Prior to 1.13.6 and 1.14.5, when an application method handler throws an uncaught error, the server includes its error message in the status message sent to the client. The thrown error message is transmitted to the client, causing sensitive information disclosure when the message contains sensitive data. This issue is fixed in versions 1.13.6 and 1.14.5.
