Technical Details

Vulnerability Mechanism & Technical Analysis

This vulnerability is classified under General Security Weakness. In Silverstripe/framework, software state validation or input boundaries are circumvented during processing. Review the official source advisory statement below for specific affected components, classes, and reproduction details.

Source Advisory Statement

"Add from URL" doesn't clearly sanitise URL server side HtmlEditorField_Toolbar has an action HtmlEditorField_Toolbar#viewfile, which gets called by the CMS when adding a media "from a URL" (i.e. via oembed). This action gets the URL to add in the GET parameter FileURL. However it doesn't do any URL sanitising server side. The current logic will pass this through to Oembed, which will probably reject most dangerous URLs, but it's possible future changes would break this.
