Stored XSS via spoofed IP headers
Published Jun 15, 2026 · Updated Jun 15, 2026
Stored XSS in CODEPRESS IT Solutions LLC SEO Redirection 9.17 and earlier allows remote attackers to inject scripts via HTTP headers. The 404 logger stores spoofable X-Forwarded-For or Client-IP values without strict IP validation, and its datagrid renders them without sufficient HTML attribute escaping. No authentication is required, but a privileged user must view affected 404-log content before the script executes in that user's browser.
