CVE-2023-46857
Squidex before 7.9.0 allows XSS via an SVG document to the Upload Assets feature.
MEDIUM 5.4EPSS 0.57%
Does this matter?
Lower severity and a low EPSS score (0.57%). Track it; it rarely justifies an emergency change on its own.
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.
