CVE-2023-46857

Exp

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.

Breaking this can reach past the original component and bite other resources—bigger blast radius.
Confidentiality (C:L)
Some sensitive info could get out, but not a total data dump.
Integrity (I:L)
Attackers could change some data, but it’s limited—not everything goes.
