Overview
Affected versions of this package are vulnerable to Information Exposure via the default exception handling process. An attacker can obtain sensitive internal exception messages by triggering an unhandled exception, causing the server to include the exception message in the EXCEPTION_WHAT response header. This is only exploitable if a custom exception handler is not registered using set_exception_handler().
