The vulnerability identified as CVE-2025-66075 affects the WP Cookie Notice for GDPR, CCPA & ePrivacy Consent plugin developed by WP Legal Pages. This plugin is widely used to manage cookie consent banners and compliance with privacy regulations such as GDPR and CCPA. The core issue is a missing authorization control, meaning that certain functions within the plugin do not properly verify whether the user has the necessary permissions before allowing access or modifications. This misconfiguration of access control security levels can be exploited by attackers to perform unauthorized actions, such as altering cookie consent settings or accessing sensitive configuration data. The affected versions include all releases up to and including 4.0.3. The vulnerability does not require prior authentication or user interaction, increasing its risk profile. Although no public exploits have been reported yet, the flaw poses a significant threat to the integrity and confidentiality of consent management processes. Since cookie consent is a critical component of privacy compliance, exploitation could lead to non-compliance with legal frameworks, exposing organizations to fines and reputational harm. The vulnerability was published on November 21, 2025, and currently lacks an assigned CVSS score or available patches, highlighting the need for immediate attention from administrators using this plugin.

For European organizations, the impact of CVE-2025-66075 can be substantial due to the critical role of cookie consent management in GDPR compliance. Unauthorized modification or disclosure of consent settings could lead to violations of privacy laws, resulting in regulatory fines and legal challenges. Additionally, compromised consent mechanisms may erode user trust and damage brand reputation. Organizations relying on this plugin for managing cookie notices risk exposure of sensitive user preferences and potential manipulation of consent records. The vulnerability could also be leveraged as a foothold for further attacks within the web environment, potentially affecting website availability or integrity. Given the widespread use of WordPress and the plugin’s focus on European privacy laws, the threat is particularly relevant to sectors handling large volumes of personal data, such as e-commerce, finance, healthcare, and public services.

1. Immediately verify the version of WP Cookie Notice for GDPR, CCPA & ePrivacy Consent installed and plan to upgrade to a patched version once released by the vendor. 2. Until a patch is available, restrict administrative access to the WordPress backend and plugin settings to trusted personnel only, employing the principle of least privilege. 3. Conduct a thorough review of user roles and permissions related to the plugin to ensure no excessive privileges are granted. 4. Monitor web server and application logs for unusual access patterns or unauthorized attempts to modify cookie consent settings. 5. Implement web application firewall (WAF) rules to detect and block suspicious requests targeting the plugin’s endpoints. 6. Prepare incident response plans specifically addressing potential exploitation of consent management vulnerabilities. 7. Stay informed through official vendor channels and security advisories for updates and patches. 8. Consider alternative cookie consent management solutions with robust access controls if patching is delayed.
