CyberRota Analysis

AI-Generated

The CustomizeUser plugin in AVideo is vulnerable to a stored cross-site scripting (XSS) attack due to the unsanitized storage of the field_name parameter. This flaw allows attackers to inject malicious scripts through the add.json.php endpoint, which can execute when users view specific pages, potentially compromising user data and session integrity. Administrators and security teams managing AVideo installations should prioritize patching this vulnerability to mitigate the risk of exploitation.
