"According to its version number, the WordPress install hosted on the
remote web server is affected by a security bypass vulnerability.
A flaw in the 'wp-admin/press-this.php' script improperly checks user
permissions when publishing posts. This allows a user with
'Contributor-level' privileges to post as if they had 'publish_posts'
permissions.
Note that Nessus has not tested for this issue but has instead relied
only on the application's self-reported version number.");
