Technical details

The Fluent Forms plugin for WordPress suffers from an incorrect authorization vulnerability (CWE-863) within its payment cancellation AJAX flow. The root cause is a failure to perform sufficient ownership validation on the 'subscription_id' parameter. An authenticated attacker with minimal privileges (Subscriber-level and above) can send a crafted AJAX request to trigger the cancellation of any subscription ID. This vulnerability is exploitable over the network without user interaction. A fix was introduced in the plugin's changeset 3513845.
