Short explanation

The MasterStudy LMS plugin versions 3.7.13 through 3.7.54 allow an authenticated Instructor to modify any registered user's first name, last name and public display name via the student‑enrollment feature without relationship verification, enabling impersonation of administrators and other users.

Why does it matter?

A privileged instructor can impersonate other accounts to conduct phishing and social‑engineering attacks.

What should be done?

  • Follow the vendor advisory when available
  • Since patch status is unknown, upgrade to the latest release once provided
  • Restrict the privileges of the Instructor role
  • Monitor changes to user profiles
  • Implement alerts for suspicious profile updates
