"The WordPress application running on the remote host has a version of the 'Yoast SEO' plugin that is prior to 22.7. It 
is, therefore, affected by a stored cross-site scripting (XSS) vulnerability due to insufficient input sanitization and 
output escaping. An authenticated attacker with contributor-level access and above could inject arbitrary web scripts in
pages that will execute whenever a user accesses an injected page.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
