CVE-2026-23880Public exploitNetwork attack vector

Administrator account takeover via unsafe name rendering

Published Jan 19, 2026 · Updated Jan 19, 2026

Stored XSS in Hack@UCF OnboardLite before commit 1d32081a allows remote authenticated users to take over an administrator account. The /admin/get_by_snowflake/ flow returns stored first and last names, and admin.js inserts them into resultsDiv with innerHTML instead of text-only DOM nodes. Exploitation requires a low-privileged user to save a name payload and an administrator to inspect that user's Discord migration record.
