EmbedPress < 4.0.5 - Missing Authorization

Description

The EmbedPress plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on several functions like get_instagram_userdata_ajax, sync_instagram_data_ajax, and delete_instagram_account in versions up to, and including, 4.0.4. This makes it possible for authenticated attackers, with subscriber-level access and above, to modify Instagram settings.
