CVE-2026-88848 Details
Description
The MasterStudy LMS WordPress plugin from 1.9 before 3.7.50 does not verify that a course a member asks to enrol in is covered by their membership plan, nor that the plan identifier submitted with the request is one they actually hold, allowing any member to enrol themselves into restricted paid courses outside their plan and beyond the number of courses it entitles them to.
A vulnerability exists in the MasterStudy LMS WordPress plugin, specifically in versions 1.9 prior to 3.7.50. The issue arises because the plugin fails to verify whether a course a member wishes to enroll in is included in their membership plan. Additionally, it does not check if the plan identifier provided with the enrollment request is one that the member actually holds. This oversight allows any member to enroll in restricted paid courses that are not covered by their plan, and to exceed the number of courses their plan allows.
Users are advised to update the MasterStudy LMS WordPress plugin to version 3.7.50 or later.
