@grpc/grpc-js is vulnerable to Information Disclosure
37
Low Risk
This Affects:
@grpc/grpc-jsTL;DR
When an application method handler throws inside @grpc/grpc-js, the server includes the thrown error's message text in the gRPC status details sent back to the client. Any sensitive data an application puts in an exception message is exposed to remote callers by default. The patch replaces the forwarded message with a generic Unknown error detail and only sends the original message when the new GRPC_NODE_DEBUG_SEND_ERROR_DETAILS environment variable is enabled.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range and a method handler in your service can throw an error whose message contains sensitive information.
Background info
@grpc/grpc-js is vulnerable to Information Disclosure in versions 0.0.1 - 1.13.5 and 1.14.0 - 1.14.4.
How to fix this
Upgrade the @grpc/grpc-js library to the patch version.
