Advisory
Source description from Wordfence Intelligence, credited to Haitam Lazaar.
The ProfilePress plugin for WordPress is vulnerable to Insecure Direct Object Reference in versions up to, and including, 4.16.16. This is due to missing ownership verification on the sub_id parameter before performing subscription actions. This makes it possible for authenticated attackers, with subscriber-level access and above, to cancel arbitrary users' subscriptions by manipulating the subscription ID parameter.
