CVE-2025-49389Network attack vector

Stored XSS via unsanitized blink speed metadata

Published Aug 20, 2025 · Updated Apr 28, 2026

Stored XSS in WEN Solutions Notice Bar 3.1.3 and earlier allows remote authenticated users to inject scripts through notice settings. The plugin stores the contributor-controlled blink_speed meta value without adequate sanitization and later places it in generated page content. Contributor access and a subsequent visitor action are required; the injected script then runs in that visitor's browser under the site's origin.
