Summary
The Simple Local Avatars plugin for WordPress is vulnerable to unauthorized modification of data in version 2.8.4. This is due to a missing capability check on the migrate_from_wp_user_avatar() function. This makes it possible for authenticated attackers, with subscriber-level access and above, to migrate avatar metadata for all users.
