Technical details
The LearnPress Sepay Payment plugin fails to perform authorization checks on a REST API endpoint that exposes order payment status. The vulnerability is in the /wp-json/learnpress-sepay/v1/lp-order endpoint, which accepts an order_id parameter and returns the order status without verifying the requester's identity or permissions. Since WordPress order IDs are sequential post IDs, an attacker can enumerate all orders on a site by iterating through ID ranges. The endpoint is network-reachable and requires no authentication, credentials, or user interaction to exploit. This vulnerability affects versions up to and including 4.0.2; a patch is available in version 4.0.3 or later.
