Attackers can craft a single GET request containing a crafted author parameter to break out of the HTML input tag and inject an img element with an onerror handler, executing arbitrary JavaScript in the victim's browser session.","summary":"e107 CMS before 2.3.13 reflects the author GET parameter in search.php into an HTML input tag without escaping.
