Subscriber content access and tampering via unchecked capabilities
Published May 2, 2024 · Updated Apr 8, 2026
Missing authorization in StylemixThemes MasterStudy LMS 3.3.8 and earlier allows remote authenticated users to read and modify course content. Several content-management handlers read or write course questions, post titles, and taxonomies without checking the caller's capability. A subscriber account is sufficient; successful requests expose, alter, or delete affected LMS data.
