Description
Squidex before 7.9.0 allows XSS via an SVG document to the Upload Assets feature. This occurs because there is an incomplete blacklist in the SVG inspection, allowing JavaScript in the SRC attribute of an IFRAME element. An authenticated attack with assets.create permission is required for exploitation.
