craftcms/cms is vulnerable to Cross-Site Scripting (XSS)
75
High Risk
This Affects:
craftcms/cmsTL;DR
The craftcms/cms control panel Craft Support widget renders documentation search hits and support-form validation errors into the DOM without escaping user- or server-influenced strings. Search result titles are inserted through jQuery html concatenation, and error messages are appended as raw HTML list items. A control panel user who can influence those values can inject script that runs in another administrator's browser session. The fix HTML-escapes search result text and uses text-node insertion for validation errors.
