It was reported , that the CGI::Application perl module suffered from a flaw where, in certain cases, it would unexpectedly dump a complete set of web query data and server environment information as an error page. This could allow unintended disclosure of sensitive information.
A suggested fix is available  and the commit that caused the problem  was most likely introduced in version 4.19.
