Unauthenticated Cross Site Scripting (XSS) in Product Filter Widget for Elementor <= 1.0.6 versions.

AnalysisAI

Reflected/stored cross-site scripting in the Product Filter Widget for Elementor WordPress plugin (versions <= 1.0.6) allows unauthenticated remote attackers to inject malicious script that executes in a victim's browser after user interaction. The flaw was disclosed via Patchstack and carries a CVSS 3.1 score of 7.1 with scope change due to script execution in the browser context; no public exploit identified at time of analysis and the vulnerability is not listed in CISA KEV.

Technical ContextAI

The affected component is a third-party WordPress plugin (vendor 'bhavin_thummar', product 'product_filter_widget_for_elementor') that extends Elementor page builder with product filtering UI for WooCommerce-style storefronts. The root cause is CWE-79 (Improper Neutralization of Input During Web Page Generation), meaning user-controlled input - likely passed through filter query parameters or widget configuration fields - is rendered back into the page DOM without adequate sanitization/encoding, allowing arbitrary HTML/JavaScript injection. Because the plugin runs on top of WordPress + Elementor, the injected payload executes in the same origin as the site, granting access to session cookies, the WordPress nonce surface, and any logged-in administrator's authenticated DOM context.

RemediationAI

Upstream fix available per Patchstack advisory; released patched version not independently confirmed from the provided data, so administrators should upgrade Product Filter Widget for Elementor to the latest version above 1.0.6 as published on the WordPress.org plugin repository and consult the Patchstack advisory at https://patchstack.com/database/wordpress/plugin/product-filter-widget-for-elementor/vulnerability/wordpress-product-filter-widget-for-elementor-plugin-1-0-6-cross-site-scripting-xss-vulnerability for the exact fixed release. If immediate patching is not possible, deactivate and remove the plugin from any production WordPress site (this disables the filter widget on product pages, which is the main functional trade-off), or place the site behind a WAF with rule sets that block reflected XSS patterns on the plugin's filter parameters (trade-off: WAF rules can produce false positives on legitimate filter queries). Additionally, enforce a strict Content-Security-Policy that disallows inline scripts on storefront pages to reduce payload execution surface, accepting that some Elementor widgets may break under strict CSP.
