CVE-2025-62924 identifies a missing authorization vulnerability in the PickPlugins Post Grid and Gutenberg Blocks plugin for WordPress, affecting versions up to 2.3.17. This vulnerability arises from incorrectly configured access control mechanisms, allowing users with limited privileges (PR:L) to perform unauthorized actions remotely (AV:N) without requiring user interaction (UI:N). The vulnerability impacts the confidentiality, integrity, and availability of affected systems, as attackers can potentially access or modify sensitive data and disrupt services. The CVSS score of 8.8 (high) reflects the severity, with an attack vector over the network, low attack complexity, and no user interaction needed. Although no exploits have been reported in the wild yet, the vulnerability's nature makes it a significant risk for WordPress sites using these plugins. The plugin is widely used to enhance content presentation via post grids and Gutenberg blocks, making it a common target for attackers seeking to leverage access control weaknesses. The lack of a patch link indicates that a fix may not yet be publicly available, emphasizing the need for vigilance and interim protective measures.

For European organizations, this vulnerability poses a substantial risk, particularly for those relying on WordPress sites enhanced with PickPlugins Post Grid and Gutenberg Blocks. Exploitation could lead to unauthorized data disclosure, data tampering, or service disruption, impacting business operations and customer trust. Sectors such as e-commerce, media, and government websites that use these plugins for content management are especially vulnerable. The breach of confidentiality could expose sensitive user or organizational data, while integrity violations could deface websites or inject malicious content. Availability impacts could result in downtime or degraded service quality, affecting reputation and revenue. Given the widespread use of WordPress across Europe, the vulnerability could have broad implications if exploited at scale.

Organizations should immediately inventory their WordPress environments to identify installations of PickPlugins Post Grid and Gutenberg Blocks. Until an official patch is released, restrict plugin usage to trusted users only and review user roles to minimize privileges. Employ web application firewalls (WAFs) with rules targeting suspicious access patterns related to the plugin's endpoints. Monitor logs for unusual activity indicative of access control bypass attempts. Consider temporarily disabling the plugin if feasible to eliminate exposure. Once a patch is available, apply it promptly and verify the fix through testing. Additionally, implement strict access control policies and conduct regular security audits of plugins and themes. Educate administrators on the risks of privilege escalation and enforce the principle of least privilege across WordPress user accounts.
