CVE-2026-88846 Details
Description
The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.50 does not check whether user registration is enabled on the site before creating an account through one of its front-end registration flows, allowing unauthenticated users to create accounts, and be logged into them, on sites where registration has been deliberately disabled.
A vulnerability exists in the MasterStudy LMS WordPress Plugin in versions prior to 3.7.50. The plugin's front-end registration processes do not verify if user registration is disabled on the site. This oversight allows unauthenticated users to create accounts and log in on sites where registration has been intentionally turned off.
Users are advised to update the MasterStudy LMS WordPress Plugin to version 3.7.50 or later.
