## Technical details

A reflected XSS vulnerability exists in the universal search page's handling of the oql_clause query parameter, where user input is reflected into the page without proper HTML sanitization. The vulnerability is in pages/UniversalSearch.php where the filter output was included directly in the HTML response without escaping. An attacker with low-privilege authentication can craft a malicious link containing JavaScript payload in the oql_clause parameter; when a victim visits the link, the script executes in their browser context with their privileges. The fix (version 3.2.3 and later) applies HTML escaping via utils::EscapeHtml() to the ToOQL() output.
