CVE-2024-3136Public exploitNetwork attack vector

Unauthenticated code execution via traversable template path

Published Apr 9, 2024 · Updated Apr 8, 2026

Local file inclusion in StylemixThemes MasterStudy LMS 3.3.3 and earlier allows remote attackers to include server files via a crafted template parameter. STM_LMS_Templates::locate_template appends the parameter to a plugin template path without blocking traversal, and load_lms_template passes the resolved file to PHP include. Exploitation requires a usable local file; uploaded files containing PHP yield code execution, while other included files can expose sensitive data or bypass access controls.
