AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:L
Remote link-based reflected XSS needs victim interaction (UI:R) and no attacker auth (PR:N); script executing in the site context crosses scope (S:C) with limited C/I/A impact.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in VillaTheme Bopo - WooCommerce Product Bundle Builder bopo-woo-product-bundle-builder allows Reflected XSS.This issue affects Bopo - WooCommerce Product Bundle Builder: from n/a through <= 1.2.0.

AnalysisAI
Reflected cross-site scripting in the VillaTheme Bopo - WooCommerce Product Bundle Builder plugin for WordPress affects all versions up to and including 1.2.0, letting unauthenticated attackers inject script into a victim's browser session when the victim clicks a crafted link. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:R/S:C) reflects a scope change, meaning injected script executes in the WordPress site's security context and can target logged-in administrators. There is no public exploit identified at time of analysis and the issue is not listed in CISA KEV, but reflected XSS in WooCommerce plugins is a well-understood and easily weaponized class.
Technical ContextAI
The affected component is a WordPress/WooCommerce extension (CPE cpe:2.3:a:villatheme:bopo_-_woocommerce_product_bundle_builder) that adds product-bundle building to WooCommerce stores. The root cause is CWE-79, Improper Neutralization of Input During Web Page Generation: user-supplied input (typically a URL/request parameter) is reflected back into an HTML response without adequate output encoding or input sanitization, so a browser interprets attacker-controlled data as executable script. Because it is reflected (non-persistent), the malicious payload travels in the request itself rather than being stored server-side, and execution requires the victim to load the attacker-crafted URL.
RemediationAI
Upgrade the Bopo - WooCommerce Product Bundle Builder plugin to a release later than 1.2.0 once VillaTheme publishes a fixed version; the input data lists affected versions only through 1.2.0 and does not include a confirmed fixed version, so this is best characterized as no vendor-released patched version independently confirmed at time of analysis - monitor the Patchstack advisory (https://patchstack.com/database/Wordpress/Plugin/bopo-woo-product-bundle-builder/vulnerability/wordpress-bopo-woocommerce-product-bundle-builder-plugin-1-2-0-reflected-cross-site-scripting-xss-vulnerability?_s_id=cve) and the WordPress.org plugin page for the fix. Until a patch is available, deploy a Web Application Firewall (Patchstack, Wordfence, or ModSecurity) with reflected-XSS rules to filter script payloads in request parameters, which adds latency and can produce false positives on legitimate rich input; alternatively, deactivate and remove the plugin if the bundle-builder feature is non-essential, which removes the store's product-bundling functionality. Enforcing a strict Content-Security-Policy that disallows inline scripts significantly reduces XSS impact but may break themes or plugins that rely on inline JavaScript.
