CVE-2025-47485 is a Missing Authorization vulnerability (CWE-862) identified in CozyThemes Cozy Blocks, a WordPress plugin used for creating custom blocks within the WordPress block editor. The vulnerability arises due to incorrectly configured access control security levels, allowing unauthorized users to exploit functionality that should be restricted. Specifically, the issue permits remote attackers to access certain features or data without proper authorization, as the plugin fails to enforce adequate permission checks. The CVSS v3.1 base score is 5.3 (medium severity), reflecting that the vulnerability can be exploited remotely over the network without authentication or user interaction, but the impact is limited to confidentiality (partial data disclosure) with no impact on integrity or availability. The affected versions include Cozy Blocks up to 2.1.22, though exact version ranges are not specified. No patches or known exploits in the wild have been reported as of the publication date (May 7, 2025). This vulnerability is significant because Cozy Blocks is widely used in WordPress sites to enhance content creation, and missing authorization can lead to unauthorized data exposure or manipulation of block configurations, potentially leaking sensitive site information or user data. However, since the impact is limited to confidentiality and no integrity or availability compromise is indicated, the threat is moderate but should be addressed promptly to prevent escalation or chaining with other vulnerabilities.

For European organizations, especially those relying on WordPress for their web presence and using CozyThemes Cozy Blocks, this vulnerability poses a risk of unauthorized data disclosure. This could include exposure of sensitive content, configuration details, or user information managed through the plugin. Such data leaks can lead to reputational damage, loss of customer trust, and potential regulatory compliance issues under GDPR, which mandates strict controls on personal data protection. Although the vulnerability does not directly allow data modification or service disruption, attackers could leverage the disclosed information for further attacks such as social engineering or privilege escalation. Organizations in sectors with high privacy requirements (e.g., finance, healthcare, government) are particularly at risk. Additionally, since the vulnerability requires no authentication or user interaction, automated scanning and exploitation attempts could increase, raising the likelihood of exploitation in the wild if unpatched. The absence of known exploits currently provides a window for mitigation before active attacks emerge.

European organizations should immediately audit their WordPress installations to identify the presence and version of CozyThemes Cozy Blocks plugin. If version 2.1.22 or earlier is in use, they should prioritize upgrading to a patched version once available from CozyThemes. In the absence of an official patch, temporary mitigations include restricting access to the WordPress admin and block editor interfaces via IP whitelisting or VPN, implementing Web Application Firewall (WAF) rules to detect and block suspicious requests targeting Cozy Blocks endpoints, and monitoring logs for unusual access patterns. Additionally, organizations should review user roles and permissions to ensure the principle of least privilege is enforced, minimizing exposure. Regular backups and incident response plans should be updated to handle potential data disclosure incidents. Security teams should subscribe to CozyThemes and CVE databases for updates on patches or exploit reports. Finally, conducting internal penetration testing focusing on authorization controls in WordPress plugins can help identify similar issues proactively.
