Description
Advanced Custom Fields before 5.7.12 fails to sanitize user-supplied input before passing it to the unserialize() function. This allows low-level authenticated users to call PHP Objects and possibly achieve remote code execution if a usable gadget is present in a plugin or theme installed on the same site as the vulnerable plugin.
