Description

The Fluent Forms Pro Add On Pack plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 6.2.6 via deserialization of untrusted input.

The additional presence of a POP chain allows attackers to change user passwords and potentially take over administrator accounts. Note: This can only be exploited if user update integration is enabled and a user meta field is mapped.
