Summary

The Flipbox Builder plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.5 via deserialization of untrusted input in the flipbox_builder_Flipbox_ShortCode function. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject a PHP Object. No known POP chain is present in the vulnerable software. If a POP chain is present via an additional plugin or theme installed on the target system, it could allow the attacker to delete arbitrary files, retrieve sensitive data, or execute code.
