Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The @grpc/grpc-js package for npm is vulnerable in versions below 1.13.6 and from 1.14.0 up to but not including 1.14.5. When an application's method handler crashes, the server may include the error message in the status message sent to the client, which can expose sensitive data contained in that message. Upgrade to 1.13.6 or 1.14.5, or add a top-level error handler in method handlers that strips sensitive details from errors.
