This cross-site request forgery vulnerability exists within the illow illow – Cookies Consent WordPress plugin, specifically impacting versions ranging from the initial release through version 0.2.0. The flaw represents a critical security weakness that allows attackers to perform unauthorized actions on behalf of authenticated users who visit malicious websites or click on compromised links. The vulnerability stems from the plugin's failure to implement proper anti-CSRF measures when processing cookie consent settings and related configuration changes.
The technical implementation of this CSRF vulnerability occurs due to the absence of anti-CSRF tokens in the plugin's administrative interfaces and API endpoints. When users access the cookie consent settings page or submit configuration changes, the plugin does not validate that requests originate from legitimate sources within the same session. This design flaw enables attackers to craft malicious requests that can modify cookie consent settings without user knowledge or explicit consent, potentially leading to unauthorized data collection or tracking activities. The vulnerability directly maps to CWE-352, which specifically addresses Cross-Site Request Forgery weaknesses in web applications.
The operational impact of this vulnerability extends beyond simple configuration changes, as it can enable attackers to manipulate cookie consent preferences in ways that may violate user privacy expectations and regulatory compliance requirements. An attacker could potentially disable cookie consent prompts, modify tracking settings, or redirect users to malicious domains while maintaining the appearance of legitimate administrative actions. This vulnerability particularly affects WordPress installations where the illow illow – Cookies Consent plugin is active, and users have administrative privileges or are logged into the WordPress admin interface.
Organizations should immediately update to the latest version of the illow illow – Cookies Consent plugin once available, as this represents the most effective immediate mitigation strategy. Additionally, implementing proper CSRF token validation mechanisms in the plugin's codebase would address the root cause of this vulnerability. Security teams should conduct comprehensive audits of all installed WordPress plugins to identify similar CSRF vulnerabilities, as the ATT&CK framework categorizes this type of weakness under T1531, which involves the use of credentials from compromised accounts. Network-level protections such as web application firewalls can provide additional defense-in-depth measures, though they should not be relied upon as primary mitigations. Regular security scanning and monitoring of WordPress installations for outdated plugins remains essential for maintaining overall security posture and preventing exploitation of similar CSRF vulnerabilities across the organization's digital infrastructure.
