GHSA-2rp4-x2j7-qmcc: Craft CMS: Stored XSS in the control panel via unescaped draft name

The control-panel helper that renders element chip/card labels writes an element’s draftName into the page without HTML-encoding it, while the surrounding path segments are encoded.

A low-privilege control-panel user who can create a draft of an element (for example, an entry) controls the draft name, so they can store an XSS payload that executes in the browser of any other control-panel user who is shown that element’s chip or card (element indexes with drafts visible, relation and element-selection fields that reference the element, and the drafts list).

This allows a low-privilege author to run JavaScript in an administrator’s authenticated session and take over the control panel. It is the same output-encoding class as the recently fixed GHSA-xrqc-p465-2xvg (Structure entry title) and GHSA-3x4w-mxpf-fhqq (revision context menu), which encoded other user-controlled titles but not the draft name.
