Summary

Apache Juneau versions through 9.2.0 are affected. The REST server sends the internal exception class and message in a "Thrown" response header on every error response, and can include internal exception messages in the error body even when stack-trace rendering is disabled (CWE-209). A remote client can read these implementation details without authentication or user interaction.
