CVE-2022-36037Network attack vector

Panel session compromise via unsafe multiselect option rendering

Published Aug 29, 2022 · Updated Apr 23, 2025

Stored XSS in Kirby 3.5.8 and earlier allows remote authenticated users to execute JavaScript in a victim's Panel session. MultiselectInput.vue inserts attacker-influenced option.info values with Vue's v-html directive, causing the dropdown to interpret stored HTML instead of displaying text. The site must use a multiselect field backed by attacker-manipulable options, and a Panel user must open its autocomplete dropdown; script execution inherits that user's API permissions.
