Technical Analysis
CVE-2026-12843 is an authorization bypass vulnerability (CWE-862) in the LearnDash LMS WordPress plugin.

This allows unauthenticated attackers to enroll arbitrary users without payment validation, effectively bypassing the payment system and gaining unauthorized access to premium educational content.
