Hero is prone to multiple cross-site scripting vulnerabilities and a cross-site request-forgery vulnerability.
An attacker can exploit these vulnerabilities to execute arbitrary script code in the browser of an unsuspecting user in the context of the affected site, steal cookie-based authentication credentials, disclose or modify sensitive information, or perform unauthorized actions. Other attacks are also possible.
Hero 3.76 is vulnerable; other versions may also be affected.
