GHSA-r97r-64vp-fghm: Silverstripe XSS vulnerability via VirtualPage

A cross-site scripting vulnerability has been discovered in the VirtualPage class.

This vulnerability can only be exploited if a user with CMS access has posted malicious or unescaped HTML into any of the textfields of a page which a VirtualPage refers to.

This has been resolved by ensuring that VirtualPage safely escapes all field content.
