Technical Summary

The LearnPress – WordPress LMS Plugin plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 4.2.6.3 due to missing validation on a user controlled key when looking up order information. This makes it possible for authenticated attackers to obtain information on orders placed by other users and guests, which can be leveraged to sign up for paid courses that were purchased by guests. Emails of other users are also exposed.

Potential Impact

Severity is MEDIUM (CVSS 6.5). Depending on deployment context, affected components may be exposed to unauthorized actions or data integrity risk.

Exploitability Assessment

Exploitability is assessed as High based on remote code execution potential.

Primary risk drivers: remote code execution potential

Mitigation Recommendations

Validate affected product versions, prioritize patching, and monitor references for vendor remediation guidance. If immediate patching is not possible, apply compensating controls and limit exposure of vulnerable surfaces.

Detection & Monitoring

Track authentication anomalies, unexpected file writes, and suspicious plugin API activity around affected components.

Business Impact Lens

Prioritize remediation where affected components process customer data, admin sessions, or Internet-exposed workflows.
