Magento is prone to multiple cross-site scripting vulnerabilities because it fails to sufficiently sanitize user-supplied input.
 
Attacker-supplied HTML and script code would execute in the context of the affected site, potentially allowing the attacker to steal cookie-based authentication credentials.
 
Magento 1.2.0 is vulnerable; other versions may also be affected.
