CVE-2025-50582Public exploitNetwork attack vector

Stored XSS via unneutralized course names

Published Jul 18, 2025 · Updated Jul 5, 2026

Stored XSS in DayCloud StudentManage 1.0 allows remote authenticated users to execute JavaScript through a crafted course name. The Add A New Course workflow accepts executable markup in the course-name field, which the course-management page renders as active content. High-privilege access is required to create the course, and another user's browser must display it; successful exploitation runs script in that user's session.
