CVE-2025-66096 identifies a missing authorization vulnerability in the Table Block by Tableberg plugin, a WordPress plugin developed by Imtiaz Rayhan. This vulnerability arises from incorrectly configured access control security levels, which allow attackers with low privileges (PR:L) to remotely exploit the plugin without requiring user interaction (UI:N). The vulnerability affects all versions up to and including 0.6.9. The CVSS v3.1 base score is 4.3, indicating a medium severity level. The attack vector is network-based (AV:N), meaning exploitation can occur remotely without physical access. The vulnerability impacts confidentiality (C:L) but does not affect integrity or availability. This suggests that unauthorized users may gain access to sensitive data or information that should be restricted but cannot modify or disrupt the system. No patches or known exploits are currently reported, indicating that the vulnerability is newly disclosed and may not yet be actively exploited. The root cause is the absence or misconfiguration of authorization checks within the plugin's code, allowing unauthorized access to certain functionalities or data. This type of vulnerability is critical in web environments where plugins extend functionality but may introduce security weaknesses if not properly secured.

For European organizations, the primary impact of CVE-2025-66096 is unauthorized disclosure of sensitive information managed or displayed via the Table Block by Tableberg plugin. Organizations using this plugin on WordPress sites that handle confidential or proprietary data risk exposure of such information to unauthorized parties. Although the vulnerability does not allow data modification or service disruption, confidentiality breaches can lead to compliance violations under GDPR and damage organizational reputation. The risk is heightened for sectors that rely heavily on web content management systems, such as e-commerce, media, education, and government services. Since exploitation requires only low privileges and no user interaction, attackers could automate scanning and exploitation attempts. The absence of known exploits currently reduces immediate risk, but the vulnerability's public disclosure increases the likelihood of future attacks. Organizations without timely patching or access control reviews may face data leakage incidents, potentially resulting in regulatory fines and loss of customer trust.

To mitigate CVE-2025-66096, European organizations should: 1) Monitor for official patches or updates from the Tableberg plugin developer and apply them promptly once available. 2) Conduct a thorough review of access control configurations within the plugin and the broader WordPress environment to ensure that authorization checks are correctly implemented and enforced. 3) Restrict plugin usage to trusted administrators and limit low-privilege user capabilities to the minimum necessary. 4) Implement web application firewalls (WAFs) with rules targeting suspicious access patterns related to the plugin's endpoints. 5) Regularly audit logs for unusual access attempts or data retrieval activities involving the plugin. 6) Consider isolating or disabling the plugin if it is not essential to reduce the attack surface. 7) Educate site administrators about the risks of misconfigured plugins and the importance of timely updates. These steps go beyond generic advice by focusing on configuration hardening, monitoring, and controlled privilege management specific to this plugin's context.
