Multiple cross-site scripting (XSS) vulnerabilities in create.php in vCard 2.x allow remote attackers to inject arbitrary web script or HTML via the (1) card_id, (2) uploaded, (3) card_fontsize, or (4) card_color parameter. NOTE: the card_id vector was later reported to affect vCard 2.9, and the uploaded vector for 2.6.
Vcard 2.9 and possibly other versions does not require authorization to run uninstall.php, which could allow remote attackers to uninstall Vcard and delete database tables via a direct request to uninstall.php.
