Medium (4.3). EPSS 0.3% chance of exploitation in the next 30 days.
The ACF Photo Gallery Field plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the "acf_photo_gallery_edit_save" function in all versions up to, and including, 3.0. This makes it possible for authenticated attackers, with subscriber level access and above, to modify the title, caption, and custom metadata of arbitrary media attachments.
