CVE-2025-0809Network attack vector

Stored XSS via unescaped broken-link output

Published Jan 31, 2025 · Updated Apr 8, 2026

Stored XSS in Keith P. Graham Link Fixer 3.4 and earlier allows remote attackers to inject scripts through crafted broken links. Broken-link processing fails to sanitize attacker-controlled link data and later renders it without sufficient output escaping, persisting executable script in a page. No authentication is required to plant the payload, which executes in a visitor's browser whenever the injected page is accessed.
