What it is

The Block Editor Gallery Slider plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the classic_gallery_slider_options() function in all versions up to, and including, 1.1.1. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update limited post meta for arbitrary posts.
