CVE-2025-66096 identifies a missing authorization vulnerability in the Table Block by Tableberg plugin, a WordPress plugin developed by Imtiaz Rayhan. The vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict unauthorized users from performing certain actions within the plugin. Specifically, versions up to and including 0.6.9 are affected, though exact version details are not fully specified. This missing authorization means that an attacker could exploit the plugin to bypass intended security restrictions, potentially accessing or modifying data they should not have permissions for. The vulnerability does not require user interaction, making it easier to exploit if the plugin is installed on a target system. No public exploits have been reported yet, and no official patches or updates have been linked at the time of publication. The lack of a CVSS score complicates severity assessment, but the nature of the vulnerability suggests a significant risk to confidentiality and integrity of data handled by the plugin. Since the plugin is a WordPress component, the threat surface is tied to WordPress installations using this plugin. The vulnerability is categorized under missing authorization, a common and critical class of security flaws that can lead to privilege escalation or unauthorized data access. The vulnerability was published on November 21, 2025, and assigned by Patchstack, a known vulnerability aggregator for WordPress plugins.

For European organizations, the impact of CVE-2025-66096 could be substantial if the Table Block by Tableberg plugin is in use. Unauthorized access to data tables managed by the plugin could lead to data leakage, unauthorized data modification, or disruption of business processes relying on the plugin's functionality. This could compromise the confidentiality and integrity of sensitive information, especially if the plugin is used in environments handling personal data or critical business information. The absence of known exploits reduces immediate risk, but the vulnerability's presence in widely used WordPress environments increases potential exposure. Organizations in sectors such as finance, healthcare, and government, which often use WordPress for content management and data presentation, may face regulatory and reputational risks if exploited. Additionally, the ease of exploitation due to missing authorization and no required user interaction means attackers could automate attacks at scale. The availability impact is likely limited unless the vulnerability is chained with other exploits to cause denial of service or data corruption. Overall, the threat could lead to unauthorized data access and manipulation, undermining trust and compliance with European data protection regulations like GDPR.

European organizations should take proactive steps to mitigate CVE-2025-66096. First, inventory all WordPress installations to identify if the Table Block by Tableberg plugin is present and determine its version. Since no official patch links are currently available, organizations should monitor vendor and security advisories closely for updates or patches and apply them immediately upon release. In the interim, restrict access to WordPress administrative interfaces and plugin management to trusted personnel only, using strong authentication and role-based access controls. Consider disabling or uninstalling the plugin if it is not essential to reduce attack surface. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the plugin's endpoints. Conduct regular security audits and penetration tests focusing on WordPress plugins and access control configurations. Enable detailed logging and monitoring to detect unauthorized access attempts or anomalous behavior related to the plugin. Educate administrators about the risks of missing authorization vulnerabilities and the importance of timely updates. Finally, consider isolating WordPress environments or using containerization to limit the impact of potential exploitation.
