CVE-2025-10588 is a medium-severity Cross-Site Request Forgery (CSRF) vulnerability affecting the PixelYourSite – Your smart PIXEL (TAG) & API Manager plugin for WordPress, specifically 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 managing GDPR-related settings within the plugin. Nonces are security tokens used to verify that requests originate from legitimate users and not from malicious third parties. Due to this flaw, an attacker can craft a malicious request that, when executed by an authenticated site administrator (e.g., by clicking a link), can modify GDPR settings without the administrator's explicit consent. This attack vector does not require the attacker to be authenticated themselves, but it does require user interaction from an administrator, such as clicking a specially crafted URL. The impact primarily affects the integrity of GDPR configurations, potentially leading to misconfigurations that could result in non-compliance or unintended data processing behaviors. Confidentiality and availability are not directly impacted. The CVSS 3.1 base score is 4.3, reflecting the ease of exploitation (no authentication needed) balanced by the requirement for user interaction and limited impact scope. No known exploits have been reported in the wild as of the publication date. The vulnerability affects all versions up to 11.1.2, and no official patches or updates are linked yet, indicating that users should monitor vendor advisories closely. Given the plugin’s role in managing tracking pixels and GDPR compliance, exploitation could undermine privacy controls and regulatory adherence on affected WordPress sites.

For European organizations, this vulnerability poses a moderate risk primarily due to its potential to alter GDPR settings without proper authorization. Since GDPR compliance is legally mandated across the EU, unauthorized changes to privacy configurations can lead to regulatory violations, fines, and reputational damage. Organizations relying on PixelYourSite for managing tracking pixels and GDPR settings may inadvertently expose user data or fail to honor user consent preferences if settings are manipulated. Although the vulnerability does not directly compromise data confidentiality or system availability, the integrity impact on privacy controls is significant. Attackers exploiting this flaw could disable or weaken GDPR protections, increasing the risk of non-compliance with data protection laws. This is especially critical for organizations processing large volumes of personal data or operating in sectors with strict privacy requirements, such as finance, healthcare, and e-commerce. The requirement for administrator interaction reduces the likelihood of widespread automated exploitation but does not eliminate risk, particularly in environments where phishing or social engineering attacks are prevalent.

1. Monitor the PixelYourSite vendor’s official channels for patches or updates addressing CVE-2025-10588 and apply them promptly once available. 2. Until a patch is released, 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 site administrators about the risks of phishing and social engineering attacks, emphasizing caution when clicking on unsolicited or suspicious links. 5. Use web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the adminEnableGdprAjax() function or unusual POST requests to the plugin’s endpoints. 6. Regularly audit GDPR settings and plugin configurations to detect unauthorized changes promptly. 7. Consider temporarily disabling or limiting the plugin’s GDPR management features if feasible until a secure version is deployed. 8. Maintain comprehensive logging and monitoring of administrative actions within WordPress to facilitate incident detection and response.
