CVE-2025-10588 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the PixelYourSite – Your smart PIXEL (TAG) & API Manager plugin for WordPress, affecting all versions up to and including 11.1.2. The vulnerability stems from missing or incorrect nonce validation in the adminEnableGdprAjax() function, which is responsible for handling GDPR-related settings via AJAX requests in the WordPress admin interface. Nonces in WordPress are security tokens used to verify that requests originate from legitimate users and prevent unauthorized actions. Due to the absence or improper implementation of nonce checks, an attacker can craft a malicious web page or email containing a forged request that, when visited or clicked by a logged-in administrator, causes the plugin to modify GDPR settings without the administrator's explicit consent. This attack vector requires user interaction (clicking a link) but does not require the attacker to be authenticated, increasing the attack surface. While the vulnerability does not expose sensitive data or disrupt service availability, unauthorized changes to GDPR settings could lead to non-compliance with data protection regulations, potentially resulting in legal and reputational consequences. The CVSS v3.1 base score is 4.3 (medium), reflecting the limited impact on confidentiality and availability but acknowledging the ease of exploitation due to lack of authentication requirements. No public exploits have been reported at this time, but the vulnerability's presence in a widely used WordPress plugin necessitates attention from site administrators and security teams.

For European organizations, the primary impact of this vulnerability lies in the potential unauthorized modification of GDPR settings within the PixelYourSite plugin. Since GDPR compliance is mandatory across the European Union and associated countries, any unauthorized changes could lead to violations of data protection laws, resulting in fines, legal actions, and damage to organizational reputation. Organizations relying on this plugin for managing tracking pixels and GDPR consent mechanisms may inadvertently expose user data or fail to honor consent preferences if settings are altered maliciously. Although the vulnerability does not directly compromise data confidentiality or availability, the indirect consequences related to regulatory compliance are significant. Additionally, attackers could leverage this vulnerability as part of a broader attack chain to weaken privacy controls or facilitate further exploitation. Given the widespread use of WordPress in Europe, especially among small and medium enterprises, the risk is non-trivial. The requirement for administrator interaction reduces the likelihood of mass exploitation but does not eliminate targeted attacks against high-value organizations or sectors with stringent privacy requirements.

1. Monitor for and apply security updates from the PixelYourSite plugin vendor promptly once patches addressing CVE-2025-10588 are released. 2. Until patches are available, restrict administrative access to trusted personnel only and enforce the principle of least privilege to minimize exposure. 3. Implement multi-factor authentication (MFA) for WordPress administrator accounts to reduce the risk of compromised credentials facilitating exploitation. 4. Educate administrators about phishing and social engineering tactics, emphasizing caution when clicking links in emails or on untrusted websites. 5. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious CSRF attempts targeting the adminEnableGdprAjax() endpoint. 6. Regularly audit GDPR settings and plugin configurations to detect unauthorized changes promptly. 7. Consider disabling or limiting the use of the PixelYourSite plugin if it is not essential, or replace it with alternatives that have stronger security postures. 8. Review and harden WordPress security configurations, including nonce implementation and AJAX request handling, to prevent similar vulnerabilities.
