One of the ways we help to improve the security of WordPress plugins, not just for our customers, but for everyone using them, is the proactive monitoring of changes made to plugins in the Plugin Directory to try to catch serious vulnerabilities.

This vulnerability could have allowed an attacker that had access to a WordPress account of contributor level or above to exploit a PHP object injection vulnerability.
