CVE-2025-50001Network attack vector

Browser script execution via undisclosed reflected input

Published Mar 19, 2026 · Updated Mar 19, 2026

Reflected XSS in tagDiv Composer 5.4.2 and earlier allows remote attackers to execute scripts when a user opens a crafted link. The public CNA and Patchstack records do not identify the vulnerable parameter, code path, or exact neutralization failure in the generated page. No authentication is required, but exploitation requires user interaction and confines the documented consequence to script execution in the affected site's browser context.
