PHPMailer reports:

Fix XSS vulnerability in one of the code examples, CVE-2017-11503. The 
code_generator.phps example did not filter user input prior to output. This 
file is distributed with a .phps extension, so it it not normally executable 
unless it is explicitly renamed, so it is safe by default. There was also an 
undisclosed potential XSS vulnerability in the default exception handler 
(unused by default). Patches for both issues kindly provided by Patrick 
Monnerat of the Fedora Project.
