DescriptionCVE.org

Incorrect Privilege Assignment vulnerability in designthemes LMS Elementor Pro lms-elementor-pro allows Privilege Escalation.This issue affects LMS Elementor Pro: from n/a through <= 1.0.4.

Executive ViewAI

Why It Matters

A critical privilege escalation vulnerability in LMS Elementor Pro (versions ≤1.0.4) allows unauthenticated attackers to gain unauthorized administrative access to learning management systems. Organizations using this plugin face immediate risk of complete system compromise, data theft, and unauthorized course/user manipulation.

Business Impact: Severe

Compensating Controls

Disable LMS Elementor Pro plugin entirely until patch is available; restrict plugin admin access to whitelist IPs only; implement WAF rules to detect and block privilege escalation payloads; enforce role-based access control (RBAC) at application layer; increase monitoring and alerting on privilege assignment changes; consider temporary migration to alternative LMS solutions if business-critical.
