## Vulnerability Details
Stored Cross Site Scripting
# Summary
A Stored Cross-Site Scripting (XSS) vulnerability exists in Classroomio LMS version 0.1.13, where the application fails to sanitize course cover image uploads.

1. Log in and go to created course or create one
2. Click on landing page
3. Click on Header > replace image cover
