This is a general community announcement for all users of WordPress/other CMS items to bring your attention to an XSS vulnerability affecting multiple WordPress plugins and themes. The vulnerability is caused by a common code pattern used in WordPress plugins and themes, thewordpress.org website and other sources.
Anyone using a WordPress or any CMS website, regardless of where the theme or plugin was sourced, needs to be aware of this and take immediate action to ensure it is secure.
As there is no simple way of knowing exactly which plugins or themes are affected, and the issue is widespread, our best advice is to periodically check for updates to any WordPress themes or plugins you are using and apply those available as soon as possible.
For updates to items obtained from other sources, please check the Plugins and Themes pages in the WordPress Admin area or the other CMS update or contact the source of the product.
We strongly recommend continuing to check for updates, especially over the next few weeks, but also on an ongoing basis. It is important to always keep your WordPress installation and associated plugins and themes up to date. If you still have concerns, we suggest engaging an experienced WordPress developer to check whether your site is affected.
Kind Regards,
Support Desk
