What an attacker can do
A remote attacker can host a page that auto-submits a forged POST to the update endpoint; when an authenticated administrator visits it, the server performs an attacker-directed download-and-deploy operation in the administrator's session — with no further interaction. Vendor/CNA’s CVSS 3.1 assessment rates confidentiality, integrity and availability impact as high.
