CVE-2023-54341Public exploitNetwork attack vectorHinoki check available

Reflected XSS via unencoded fileviewer title input

Published Jan 13, 2026 · Updated Jan 13, 2026

Reflected XSS in jokkedk Webgrind 1.1 and earlier allows remote attackers to execute JavaScript in a victim's browser via a crafted URL. The fileviewer path in index.php places the unencoded file parameter inside the page title, letting a closing title tag introduce script markup. No account is required, but a victim must open the crafted link; resulting script execution is limited to the Webgrind origin and the victim's browser context.
