CVE-2026-1421Public exploitNetwork attack vector

Stored XSS via unneutralized Add Pages input

Published Jan 26, 2026 · Updated Jan 26, 2026

Stored XSS in Code Projects Online Examination System 1.0 allows remote authenticated users to inject script through Add Pages forms. The add_visitor.php, add_offering.php, add_teen.php, and admin_user.php forms store submitted field values without neutralizing them before later page generation. Low-privileged access is required, and the script runs only when another user views an affected record, allowing page content to be altered in that user's browser.
