CVE-2023-6494Network attack vector

Stored XSS via unsanitized admin settings

Published Apr 13, 2024 · Updated Apr 8, 2026

Stored XSS in WPClever WPC Smart Quick View for WooCommerce 4.0.2 and earlier allows remote authenticated users to inject scripts via admin settings. The settings path stores administrator-supplied values without sufficient input sanitization and renders them without output escaping; the published description does not identify a specific setting or function. Exploitation requires administrator-level access and is limited to WordPress multisite installations or installations where unfiltered_html is disabled; injected scripts execute when a user opens an affected page.
