CVE-2025-23821 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the aleapp WP Cookies Alert WordPress plugin, specifically affecting versions up to 1.1.1. CSRF vulnerabilities occur when a web application does not sufficiently verify that requests to perform state-changing actions originate from legitimate users, allowing attackers to craft malicious web pages that cause authenticated users to unknowingly execute unwanted actions. In this case, the WP Cookies Alert plugin lacks adequate CSRF protections, enabling attackers to potentially alter cookie consent settings or other plugin-related configurations by sending crafted requests that the victim's browser executes with their privileges. The plugin is used to display cookie consent alerts to comply with privacy regulations such as GDPR. While no public exploits have been reported, the vulnerability could be exploited in targeted attacks against websites using this plugin. The absence of a CVSS score indicates that the vulnerability's impact and exploitability have not been fully quantified, but the technical details confirm the presence of a CSRF flaw. The vulnerability requires the victim to be authenticated on the affected WordPress site, limiting the attack surface to logged-in users, typically administrators or editors who can modify plugin settings. The vulnerability was published on January 16, 2025, by Patchstack, with no patch links currently available, suggesting that a fix is pending or in development. This vulnerability highlights the importance of implementing anti-CSRF tokens and verifying request origins in WordPress plugins that perform state-changing operations.

The primary impact of this CSRF vulnerability is the unauthorized modification of cookie alert settings on affected WordPress sites, which could lead to incorrect or misleading cookie consent notices being displayed to end users. This may result in non-compliance with privacy laws such as GDPR or CCPA, exposing organizations to regulatory penalties and reputational damage. Additionally, if the plugin controls other sensitive settings, attackers could manipulate site behavior or user experience. Since exploitation requires an authenticated user session, the risk is somewhat mitigated but remains significant for sites with multiple administrators or editors. The vulnerability does not directly expose confidential data or allow remote code execution, limiting its impact on confidentiality and availability. However, the integrity of site configurations and compliance mechanisms can be compromised, which is critical for organizations relying on accurate cookie consent management. Organizations worldwide using this plugin, especially those in regions with strict privacy regulations, face potential legal and operational risks if the vulnerability is exploited.

Organizations should immediately audit their WordPress installations to identify if the WP Cookies Alert plugin version 1.1.1 or earlier is in use. Until an official patch is released, administrators can mitigate risk by restricting plugin management capabilities to the minimum necessary users and educating users about the risks of interacting with untrusted websites while authenticated. Implementing Web Application Firewall (WAF) rules to detect and block suspicious POST requests targeting the plugin’s endpoints can reduce exploitation chances. Site owners should monitor logs for unusual requests that could indicate CSRF attempts. Developers and site administrators should ensure that all state-changing requests include anti-CSRF tokens and validate the origin of requests. Once a patch is available, prompt updating of the plugin is critical. Additionally, reviewing and hardening user roles and permissions within WordPress can limit the impact of potential exploitation. Regular security assessments and plugin updates remain essential best practices.
