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

Collected exploitation and prediction evidence

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

Published

@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.

### Impact If an application method handler crashes, the error message is included in the status message sent to the client. This can leak to the client any sensitive data that may be included in the error message. This impacts anyone using `@grpc/grpc-js` to run servers. ### Patches This vulnerability is fixed in 1.13.6 and 1.14.5. ### Workarounds This can be avoided by using a top-level error handler in method handlers to strip out sensitive error information.
