CVE-2026-7648: CWE-639 Authorization Bypass Through User-Controlled Key in thimpress LearnPress – WordPress LMS Plugin for Create and Sell Online Courses
LearnPress WordPress LMS Plugin versions up to 4. 3. 5 contains an authorization bypass vulnerability allowing authenticated users with subscriber-level access or higher to enroll in paid courses without payment. This occurs because the REST API endpoint improperly handles user-supplied parameters, enabling attackers to set the quantity to zero, which results in a zero-dollar order total and bypasses payment gateway requirements.
AI Analysis
Technical Summary
CVE-2026-7648 is an authorization bypass vulnerability in the LearnPress WordPress LMS Plugin for Create and Sell Online Courses. The issue arises from improper sanitization of user-controlled request parameters in the REST API endpoint. These parameters are passed unsanitized to the add_to_cart() function, where array_merge() allows attacker-controlled values to overwrite hardcoded defaults. This flaw enables authenticated users with subscriber-level privileges or higher to manipulate the quantity parameter to zero, causing the order total to be calculated as $0 and bypassing payment processing for paid courses.
Potential Impact
An attacker with subscriber-level access or higher can enroll in paid courses without paying by exploiting this vulnerability. This results in loss of revenue for course providers and undermines the integrity of the payment system. There is no direct impact on confidentiality or availability reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict subscriber-level access where possible and monitor for suspicious enrollment activity. Avoid relying solely on client-supplied parameters for payment calculations.
