CVE-2022-31023Network attack vector

Sensitive data disclosure via verbose production errors

Published Jun 2, 2022 · Updated Apr 23, 2025

Information disclosure in Play Framework before 2.8.16 allows remote attackers to read sensitive stack-trace data from error responses. The Scala DefaultHttpErrorHandler object always renders verbose errors and was the default for CORSFilter and CORSActionBuilder APIs. Exposure requires a production application to use that static object or an improperly configured injected error handler.
