The Grid Gallery – Photo Image Grid Gallery plugin for WordPress is vulnerable to PHP Object Injection in all versions up to, and including, 1.4.3 via deserialization via shortcode of untrusted input from the awl_gg_settings_ meta value. This makes it possible for authenticated attackers, with contributor access and above, to inject a PHP Object. No POP chain is present in the vulnerable plugin.
