## Summary A low-privileged user can craft a malicious uploaded SVG image that submits a POST request to an arbitrary backend endpoint when a user (including administrator) opens it in a separate browser tab and clicks the image. By tricking an administrator into opening a link and clicking on the image, an attacker can execute actions with administrator privileges, including elevating their own account to administrator.

No affected version ranges are stored yet. Use the vendor advisory before you decide this record does not apply.
