Technical details
The AxiomThemes 777 (triple-seven) theme for WordPress contains a PHP Object Injection vulnerability due to the deserialization of untrusted data (CWE-502). An unauthenticated remote attacker can exploit this by submitting specially crafted input to a vulnerable component that uses the PHP unserialize() function.
