Impact

The MasterStudy LMS WordPress Plugin does not check whether WordPress site registration is enabled before creating a user account through its front‑end registration flow, allowing an unauthenticated visitor to submit the registration form and receive a logged‑in account even when the WordPress setting that allows anyone to register has been disabled.

Affected Systems

WordPress installations that use the MasterStudy LMS plugin version older than 3.7.50 are affected. The flaw exists when the plugin’s registration pages are accessible, even if WordPress user registration is disabled.

Risk and Exploitability

This vulnerability can be exploited remotely via the plugin’s public registration endpoints. The CVSS score is 5.3 and the EPSS score is < 1 %, indicating a moderate threat level.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Upgrade the MasterStudy LMS WordPress Plugin to version 3.7.50 or later, which removes the flaw.
  • If an upgrade is not immediately possible, block the plugin’s front‑end registration URLs using a firewall rule or a security plugin, preventing new account creation from the web interface.
  • Disable the WordPress setting that allows anyone to register and restrict user role promotions so that only administrators can grant elevated privileges.
