CVE-2023-6828Network attack vector

Unauthenticated stored XSS via unsanitized referrer URL

Published Jan 11, 2024 · Updated Apr 8, 2026

Stored cross-site scripting in ARForms 1.5.8 and earlier allows remote attackers to inject scripts through arf_http_referrer_url. The plugin accepts that referrer parameter without sufficient input sanitization and later renders the stored value without output escaping. No authentication is required to submit the payload, but script execution occurs only when a user opens an injected page.
