CVE-2026-23695: Cockpit CMS: Stored cross-site scripting vulnerability in the Set field type's Display template option

Cockpit CMS through version 2.14.0, patched in commit 72a83fc, contains a stored cross-site scripting vulnerability in the Set field type’s Display template option, where the template string is processed by the $interpolate function using new Function() and rendered via Vue’s v-html directive without sanitization. An attacker with content/:models/manage permission can inject arbitrary JavaScript into the Display template, which executes in the browser of any user viewing the collection items list.
