CVE-2025-30805 identifies a Cross-Site Request Forgery (CSRF) vulnerability in the wpdesk Flexible Cookies WordPress plugin, specifically affecting versions up to 1.1.8. CSRF vulnerabilities occur when a web application does not adequately verify that requests modifying state originate from legitimate users, allowing attackers to craft malicious requests that an authenticated user unknowingly executes. In this case, the Flexible Cookies plugin, which manages cookie consent and related settings on WordPress sites, fails to implement proper anti-CSRF tokens or equivalent protections on sensitive endpoints. As a result, an attacker can induce an authenticated administrator or user with sufficient privileges to perform unintended actions, such as changing cookie consent configurations or other plugin settings. This can undermine user privacy controls or disrupt site functionality. The vulnerability does not require user interaction beyond the victim being logged in, and no authentication bypass is indicated, meaning the attacker must trick an authenticated user into visiting a malicious page. No CVSS score is assigned yet, and no known exploits have been reported. The vulnerability was published on March 27, 2025, and is tracked under CVE-2025-30805. The plugin is widely used in WordPress environments, which are popular globally, especially in countries with strict privacy regulations. The lack of a patch link suggests that a fix may be pending or needs to be applied manually by site administrators.

The primary impact of this CSRF vulnerability is the unauthorized modification of cookie consent settings or other configurations managed by the Flexible Cookies plugin. This can lead to violations of user privacy preferences, potentially exposing organizations to legal and regulatory risks, especially in jurisdictions with stringent data protection laws such as GDPR in the EU. Additionally, attackers could disrupt website functionality or user experience by altering cookie behavior, which may affect site analytics, advertising, or compliance mechanisms. Since exploitation requires an authenticated user, the scope is limited to sites where attackers can lure logged-in users (e.g., administrators or editors) to malicious sites. However, given the widespread use of WordPress and the plugin, the potential reach is significant. Organizations relying on this plugin risk reputational damage and compliance penalties if the vulnerability is exploited. The absence of known exploits reduces immediate risk but does not eliminate the threat, as attackers may develop exploits once the vulnerability is public.

To mitigate this vulnerability, organizations should first verify the version of the wpdesk Flexible Cookies plugin in use and upgrade to a patched version once it becomes available. In the absence of an official patch, administrators can implement manual CSRF protections by ensuring that all state-changing requests require valid nonce tokens or similar anti-CSRF mechanisms. Restricting administrative access and enforcing the principle of least privilege can reduce the risk of exploitation by limiting the number of users who can perform sensitive actions. Additionally, educating users about the risks of visiting untrusted websites while logged into administrative accounts can help prevent CSRF attacks. Monitoring web server logs and WordPress activity logs for unusual changes to cookie settings or plugin configurations may help detect exploitation attempts. Finally, applying a web application firewall (WAF) with CSRF protection rules can provide an additional layer of defense.
