What it is

The ACF Flexible Layouts Manager plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'acf_flm_update_template_with_pasted_layout' function in all versions up to, and including, 1.1.6. This makes it possible for unauthenticated attackers to update custom field values on individual posts and pages.
