CVE-2025-6201 is a Stored Cross-Site Scripting (XSS) vulnerability identified in the Pixel Manager for WooCommerce – Track Conversions and Analytics, Google Ads, TikTok and more plugin for WordPress, developed by alekv. This vulnerability affects all versions up to and including 1.49.0. The root cause is improper neutralization of input during web page generation (CWE-79), specifically due to insufficient input sanitization and output escaping on user-supplied attributes within the plugin's conversion-pixel functionality. An authenticated attacker with contributor-level permissions or higher can exploit this vulnerability by injecting arbitrary malicious scripts into pages managed by the plugin. These scripts execute in the context of any user who views the compromised page, potentially leading to session hijacking, privilege escalation, or unauthorized actions within the affected WordPress site. The vulnerability does not require user interaction beyond page access, and the attack vector is remote network-based with low attack complexity. The CVSS v3.1 base score is 6.4 (medium severity), reflecting limited confidentiality and integrity impact but no availability impact. No known exploits are currently reported in the wild, and no patches have been officially released as of the publication date (June 19, 2025).

For European organizations using WooCommerce with the Pixel Manager plugin, this vulnerability poses a significant risk to the confidentiality and integrity of their e-commerce platforms. Attackers with contributor-level access can inject malicious scripts that execute in the browsers of site visitors or administrators, potentially leading to theft of authentication tokens, manipulation of analytics data, or unauthorized actions such as fraudulent transactions or data leakage. This can damage customer trust, lead to regulatory non-compliance (e.g., GDPR breaches due to data exposure), and cause financial losses. Given WooCommerce's widespread adoption in Europe, especially among small and medium-sized enterprises (SMEs) relying on WordPress for online sales, the threat surface is substantial. The vulnerability's exploitation could also facilitate further attacks within the organization's network if administrative credentials are compromised. However, the requirement for contributor-level access limits the attacker's initial entry point, somewhat reducing the risk from external unauthenticated attackers but emphasizing the need for strict access controls internally.

Immediately restrict contributor-level and higher permissions to trusted users only, enforcing the principle of least privilege. Implement strict input validation and output encoding on all user-supplied data fields related to the Pixel Manager plugin, either by applying custom hardening or awaiting an official patch from the vendor. Monitor WordPress user activity logs for unusual contributor-level actions that may indicate exploitation attempts. Use Web Application Firewalls (WAFs) with custom rules to detect and block suspicious payloads targeting the conversion-pixel parameters. Regularly audit installed WordPress plugins and remove or disable any unnecessary or outdated plugins, especially those without active maintenance. Educate site administrators and contributors on the risks of XSS and safe content management practices. Backup website data frequently to enable quick restoration in case of compromise. Track vendor communications for patch releases and apply updates promptly once available.
