CVE-2026-118983 · Severity: info · Published 2026-11-04

VikWidgetsLoader is a WordPress plugin that provides visual widgets through block components. The plugin fails to properly sanitize certain block attributes before displaying them in HTML, allowing users with Contributor role permissions to inject malicious JavaScript code that executes when administrators, editors, or other users view posts containing the infected widget—potentially leading to account compromise or data theft.
