CVE-2026-75078Public exploitNetwork attack vector

Unauthenticated XSS via unsanitized course parameter

Published Aug 17, 2026 · Updated Aug 19, 2026

Cross-site scripting in SourceCodester Class and Exam Timetabling System 1.0 allows remote attackers to run script in a victim's browser via course. BSHRM1.php reflects the course parameter into page output without output encoding or input filtering, so crafted HTML or JavaScript is returned to the browser and executes in the application's origin. The public proof of concept states that no login is required, but exploitation still depends on a user loading the tainted page and is bounded to browser-side script execution in that session context.
