Technical details

The LearnPress plugin (up to version 4.3.5) is vulnerable to an authorization bypass (CWE-639) due to improper handling of user-supplied parameters in its REST API endpoint. Specifically, the REST API passes unsanitized input to the add_to_cart() function, where an array_merge() call allows user-controlled values to overwrite hardcoded defaults. An authenticated attacker with subscriber-level permissions can exploit this by submitting a quantity value of zero. This causes the internal order calculation to result in a $0 total, effectively bypassing payment gateway requirements and granting free access to paid courses.
