Authenticated script execution via unencoded announcements

Published Feb 8, 2026 · Updated Feb 8, 2026

Stored XSS in Code Projects Online Student Management System 1.0 allows remote authenticated users to run scripts in viewers' browsers. The add-announcement handler stores the announcement content parameter and later renders it on announcement pages without sanitization or output encoding. Administrator access is required to plant the payload; it executes for later viewers with their browser-session privileges.
