CVE-2026-7804Network attack vector

Reflected script execution via unescaped wpf_fid parameter

Published Sep 9, 2026 · Updated Sep 9, 2026

Reflected cross-site scripting in WooBeWoo Product Filter for WooCommerce by WBW 3.4.2 and earlier allows remote attackers to execute scripts. The plugin accepts the wpf_fid request parameter without sufficient sanitization and emits it in filter recalculation output without proper escaping. Exploitation requires a crafted request to reach a page containing the affected filter output and a user to follow the link; the injected script then runs in that user's browser.
