Technical details
The book-detail page template in site/views/view_book/tmpl/default.php echoes the title request parameter directly into a double-quoted HTML attribute without escaping, allowing an attacker to break out of the attribute with a double-quote character and inject arbitrary HTML and JavaScript. The vulnerability is a reflected XSS (CWE-79) requiring only a crafted URL and no authentication; the attacker's payload executes in the context of the victim's browser if they visit the malicious link. A fix is available in version 6.4.6 and later.
