CVE-2026-81197Network attack vectorHinoki check available

Unauthenticated draft course disclosure via unfiltered REST listing

Published Sep 2, 2026 · Updated Sep 2, 2026

Information disclosure in StylemixThemes MasterStudy LMS before 3.7.46 allows remote attackers to read unpublished course titles and IDs. The course-list REST route neither restricts unauthenticated access nor filters its author-course query by publication status. No account or user interaction is required; draft, pending, and private course metadata is exposed, but course content is not reported as accessible.
