What it is

The MasterStudy LMS WordPress Plugin WordPress plugin before 3.7.55 does not verify that a user targeted through its student-enrolment feature has any relationship to the requesting instructor, allowing users with the Instructor role to overwrite the first name, last name and public display name of any registered user on the site, including administrators, enabling impersonation and phishing.
