Silverstripe XSS in shortcodes

Check your stack

The advisory, in context

A malicious content author could add arbitrary attributes to HTML editor shortcodes which could be used to inject a JavaScript payload on the front end of the site. The shortcode providers that ship with Silverstripe CMS have been reviewed and attribute whitelists have been implemented where appropriate to negate this risk.

Affected packages

Start with the recorded fix for your release branch. Check your installed version and test compatibility before upgrading. Fixing this advisory does not rule out other vulnerabilities in the release.
