CVE-2025-62924 identifies a missing authorization vulnerability in the PickPlugins Post Grid and Gutenberg Blocks WordPress plugin, specifically affecting versions up to 2.3.17. The vulnerability arises from incorrectly configured access control security levels, which fail to properly verify whether a user has the necessary permissions to perform certain actions within the plugin. This can allow unauthorized users to exploit the plugin's functionalities, potentially leading to unauthorized content manipulation or exposure. The plugin integrates with the Gutenberg editor, a core WordPress content editing framework, and is used to create and manage post grids and blocks on WordPress sites. Since the vulnerability does not require authentication or user interaction, it could be exploited remotely by unauthenticated attackers if the plugin is active and accessible. No CVSS score has been assigned yet, and no known exploits have been reported in the wild. However, the nature of the vulnerability suggests a significant risk, especially for websites relying on this plugin for content presentation. The lack of patches at the time of publication necessitates immediate attention to plugin version management and access controls. The vulnerability is cataloged by Patchstack and publicly disclosed on October 27, 2025.

For European organizations, this vulnerability poses a risk to the confidentiality and integrity of web content managed via WordPress sites using the affected plugin. Unauthorized users could manipulate or access content grids, potentially defacing websites, exposing sensitive information, or disrupting content delivery. This can damage organizational reputation, lead to data breaches, or facilitate further attacks such as phishing or malware distribution. Given the widespread use of WordPress and Gutenberg in Europe, especially among SMEs and content-heavy enterprises, the impact could be broad. The absence of authentication requirements lowers the barrier for exploitation, increasing risk. Additionally, compromised content management systems can affect availability indirectly by forcing site downtime for remediation. Organizations in sectors such as media, e-commerce, education, and government, which heavily rely on WordPress for public-facing content, are particularly vulnerable.

1. Immediately audit WordPress installations to identify the presence and version of the PickPlugins Post Grid and Gutenberg Blocks plugin. 2. Restrict plugin management and content editing privileges strictly to trusted administrators and editors. 3. Monitor web server and application logs for unusual or unauthorized access attempts related to the plugin endpoints. 4. Until an official patch is released, consider disabling or uninstalling the affected plugin if feasible. 5. Implement Web Application Firewall (WAF) rules to block suspicious requests targeting the plugin’s functionalities. 6. Educate site administrators about the risks of unauthorized plugin access and enforce strong authentication mechanisms for WordPress admin accounts. 7. Regularly check for vendor updates or security advisories from PickPlugins and apply patches promptly once available. 8. Employ security plugins that can detect and alert on unauthorized changes to WordPress content or plugin files.
