CVE-2024-0386Network attack vector

Unauthenticated stored XSS via unsanitized Referer header

Published Mar 12, 2024 · Updated Apr 8, 2026

Stored XSS in BoldGrid weForms 1.6.21 and earlier allows remote attackers to inject scripts through a crafted Referer header. Form-submission handling stores the unsanitized header in entry and notification data, and affected views render it without output escaping. No authentication is required to submit the header; the script runs when a user opens the poisoned entry or notification view, enabling actions in that user's browser context.
