Detailsinfo

A vulnerability was found in ThimPress LearnPress Plugin up to 4.3.5 on WordPress. It has been classified as critical. Affected is the function add_to_cart of the component REST API Endpoint. The manipulation with an unknown input leads to a authorization vulnerability. CWE is classifying the issue as CWE-639. The system's authorization functionality does not prevent one user from gaining access to another user's data or record by modifying the key value identifying the data. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

The LearnPress – WordPress LMS Plugin for Create and Sell Online Courses plugin for WordPress is vulnerable to payment bypass through user-controlled key in all versions up to, and including, 4.3.5. This is due to improper handling of user-supplied request parameters in the REST API endpoint, which passes the unsanitized parameter array to the add_to_cart() function where array_merge() allows attacker-controlled values to overwrite hardcoded defaults. This makes it possible for authenticated attackers, with subscriber-level access and above, to enroll in any paid course entirely free of charge by supplying a quantity value of zero, which causes the order total to calculate as $0 and bypasses all payment gateway requirements.

The weakness was shared by winrace. The advisory is shared for download at wordfence.com. This vulnerability is traded as CVE-2026-7648 since 05/01/2026. The exploitability is told to be easy.
