CVE-2023-45303
ThingsBoard before 3.5 allows Server-Side Template Injection if users are allowed to modify an email template, because Apache FreeMarker supports freemarker.template.utility.Execute (for content sent to the /api/admin/settings endpoint).
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.86%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
