CVE-2025-14280 is a vulnerability classified under CWE-200 (Exposure of Sensitive Information to an Unauthorized Actor) affecting the PixelYourSite plugin for WordPress, a tool widely used for managing tracking pixels and APIs. The issue arises from publicly exposed log files generated when the 'Meta API logs' feature is enabled. These log files can contain sensitive information such as API keys, user identifiers, or other metadata related to tracking and analytics. Because the logs are publicly accessible without authentication or user interaction, any unauthenticated attacker can retrieve this information simply by accessing the log file URLs. The vulnerability affects all versions up to and including 11.1.5. While version 11.1.5 introduced a partial patch, the complete fix was implemented in version 11.1.5.1. The CVSS 3.1 base score is 5.3, indicating medium severity, with the vector AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N, meaning the attack can be performed remotely with low complexity, no privileges, and no user interaction, impacting confidentiality only. No integrity or availability impacts are noted. No known exploits have been reported in the wild, but the exposure of sensitive information could facilitate further attacks such as targeted phishing or account takeover if attackers leverage leaked API keys or tokens. The vulnerability is particularly relevant for websites that enable detailed logging for debugging or monitoring purposes without restricting access to the logs. Since PixelYourSite is a popular plugin for marketing and analytics, the exposure of tracking data can have privacy and compliance implications, especially under GDPR regulations in Europe.

For European organizations, the primary impact is the unauthorized disclosure of sensitive information contained in the PixelYourSite plugin's log files. This could include API keys, user tracking data, or other metadata that may be leveraged for further attacks such as impersonation, data harvesting, or targeted phishing campaigns. Although the vulnerability does not directly affect system integrity or availability, the confidentiality breach can undermine customer trust and lead to regulatory penalties under GDPR if personal data is exposed. Organizations relying on PixelYourSite for marketing analytics and pixel management may face reputational damage and operational disruptions if attackers exploit this vulnerability to gather intelligence or compromise related systems. The risk is heightened for e-commerce, media, and marketing companies that extensively use WordPress and PixelYourSite, especially if they have enabled the 'Meta API logs' feature without proper access controls. Additionally, attackers could use exposed API keys to manipulate tracking data or gain indirect access to other integrated services, compounding the impact.

1. Immediately update the PixelYourSite plugin to version 11.1.5.1 or later, which contains the full patch for this vulnerability. 2. Verify that the 'Meta API logs' setting is disabled unless absolutely necessary; if logging is required for troubleshooting, ensure that log files are stored securely and access is restricted via web server configurations or authentication mechanisms. 3. Implement strict access controls on directories containing log files, using .htaccess rules or equivalent web server settings to prevent public access. 4. Regularly audit and monitor web server logs and plugin configurations to detect any unauthorized access attempts to log files. 5. Rotate any potentially exposed API keys or tokens immediately after patching to prevent misuse. 6. Educate site administrators about the risks of enabling verbose logging features without proper security measures. 7. Employ web application firewalls (WAF) to block suspicious requests targeting log file paths. 8. Conduct periodic vulnerability scans and penetration tests focusing on plugin configurations and exposed resources. 9. Review privacy policies and data processing agreements to ensure compliance with GDPR regarding data exposure incidents. 10. Maintain an incident response plan to quickly address any exploitation attempts related to this vulnerability.
