Stored XSS via unneutralized Description content

Published Mar 27, 2026 · Updated Mar 27, 2026

Stored XSS in Code Projects Online Reviewer System 1.0 allows remote authenticated users to inject scripts through the Description field. The student assessment databank handler retains attacker-controlled Description content and renders it as active browser code without neutralization. High-privilege access is required to submit the payload, and another user's interaction is required before the stored script can alter content in that browser session.
