Authenticated stored XSS via unescaped post content
Published Feb 3, 2026 · Updated Feb 3, 2026
Stored XSS in Ajay D'Souza Better Search 4.2.1 and earlier allows remote authenticated users to execute scripts through crafted post content. The plugin accepts script-bearing content from Author-level users and later renders it without sufficient input sanitization or output escaping. Author-level access is required, and execution occurs in the browser of a user who views the injected page, exposing that user's site privileges and data.
