CVE-2025-6461 is an information exposure vulnerability classified under CWE-200 affecting the CubeWP – All-in-One Dynamic Content Framework plugin for WordPress, specifically versions up to and including 1.1.27. The flaw resides in the search feature implemented in the class-cubewp-search-ajax-hooks.php file, where insufficient access control allows unauthenticated attackers to retrieve content from posts that should be restricted, including password-protected, private, or draft posts. This occurs because the search functionality does not properly enforce permission checks before returning post data, leading to unauthorized disclosure of sensitive information. The vulnerability can be exploited remotely without authentication or user interaction, making it accessible to any attacker with network access to the affected WordPress site. Although the impact is limited to confidentiality, as integrity and availability are not affected, the exposure of sensitive content can lead to privacy violations, leakage of proprietary or personal data, and potential reputational damage. The CVSS v3.1 base score is 4.3, indicating a medium severity level, with the vector AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N, meaning network attack vector, low attack complexity, requires low privileges (authenticated user), no user interaction, unchanged scope, and low confidentiality impact. However, the description states unauthenticated attackers can exploit it, suggesting a possible discrepancy in the CVSS vector or that some level of privilege is needed. No patches or fixes have been officially released at the time of publication, and no known exploits are reported in the wild. Organizations using CubeWP should consider this vulnerability seriously due to the potential exposure of sensitive content.

For European organizations, the primary impact of CVE-2025-6461 is the unauthorized disclosure of sensitive or confidential information stored within WordPress sites using the CubeWP Framework plugin. This can include internal documents, draft content, private communications, or any data intended to be restricted. Such exposure can lead to privacy breaches, intellectual property theft, compliance violations (e.g., GDPR), and reputational harm. Although the vulnerability does not affect data integrity or system availability, the confidentiality breach alone can have significant consequences, especially for sectors handling sensitive data such as finance, healthcare, legal, and government. The ease of exploitation without authentication increases the risk profile, as attackers can automate data extraction at scale. European organizations relying on WordPress for content management and using CubeWP are advised to assess their exposure promptly. The lack of known exploits in the wild currently provides a window for mitigation before active exploitation occurs.

1. Immediately audit all WordPress sites using the CubeWP Framework plugin to identify affected versions (up to 1.1.27). 2. Disable or deactivate the CubeWP plugin temporarily if the site contains sensitive or private content until a security patch is released. 3. Implement strict access controls on the search functionality, such as restricting search queries to authenticated users with appropriate permissions or disabling AJAX search features that expose post data. 4. Use Web Application Firewalls (WAFs) to monitor and block suspicious search requests that attempt to access unauthorized content. 5. Regularly monitor WordPress plugin updates and apply security patches promptly once available from the vendor. 6. Conduct internal security reviews of custom plugins or themes that interact with CubeWP to ensure no additional exposure vectors exist. 7. Educate content managers and administrators about the risks of storing sensitive information in draft or private posts without adequate protection. 8. Consider implementing content encryption or additional authentication layers for highly sensitive data within WordPress. 9. Review and tighten WordPress user roles and permissions to minimize privilege escalation risks. 10. Maintain comprehensive logging and alerting to detect unusual access patterns related to the search feature.
