Missing escaping in the Viewpdf macro allows any user with view right on the `CKEditor.HTMLConverter` page or edit or comment right on any page to perform remote code execution.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.06%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
