What is CVE-2026-81197?

The MasterStudy LMS WordPress Plugin prior to version 3.7.46 has a security flaw that allows unauthorized access to a REST endpoint. This vulnerability enables unauthenticated users to view the titles and IDs of unpublished courses, including drafts, pending, and private listings. The absence of access restrictions poses a significant risk, as it potentially exposes sensitive content to users who should not have visibility into unpublished materials.
