Overview
CVE-2025-66096 describes a “Missing Authorization” vulnerability found in the Table Block by Tableberg plugin for WordPress, also known as tableberg. This flaw allows attackers to potentially exploit incorrectly configured access control security levels, leading to unauthorized access and manipulation of data. The vulnerability affects versions of the Tableberg plugin up to and including 0.6.9.
Technical Details
The vulnerability stems from a lack of proper authorization checks within the Tableberg plugin. This means that certain functionalities, such as creating, modifying, or deleting tables, may not be adequately protected against unauthorized users. An attacker could potentially leverage this flaw to bypass intended access controls and perform actions they are not permitted to, potentially leading to data breaches, defacement of websites, or other malicious activities.
Specifically, the issue is classified as “Exploiting Incorrectly Configured Access Control Security Levels.” This likely means the plugin relies on access controls, but these controls are either flawed in their logic, incorrectly implemented, or easily bypassed.
CVSS Analysis
According to the information available, the CVSS score is currently listed as N/A (Not Available). Similarly, the severity is also marked as N/A. While this might suggest a low-impact issue, it’s crucial to investigate further, especially if you are using the affected Tableberg plugin. The lack of a CVSS score doesn’t negate the existence of the vulnerability; it might simply mean it hasn’t been formally assessed yet.
Possible Impact
The potential impact of CVE-2025-66096 could be significant, depending on the specific implementation and configuration of the Tableberg plugin on the affected WordPress website. Possible consequences include:
- Data Breach: Unauthorized access to sensitive data stored within tables.
- Website Defacement: Modification or deletion of table content, leading to website defacement.
- Privilege Escalation: An attacker could potentially escalate their privileges to gain administrative access to the WordPress website.
- Denial of Service (DoS): An attacker could potentially disrupt the normal functioning of the website by manipulating tables or causing errors.
Mitigation or Patch Steps
The primary mitigation step is to update the Table Block by Tableberg plugin to the latest version as soon as a patch is available. Check the WordPress plugin repository or the plugin developer’s website for updates.
In the meantime, while waiting for an official patch, consider the following:
- Disable the plugin: If the Tableberg plugin is not essential to your website’s functionality, temporarily disable it until a patch is released.
- Monitor User Activity: Closely monitor user activity on your WordPress website for any suspicious behavior.
- Implement Web Application Firewall (WAF) rules: If you use a WAF, consider implementing custom rules to detect and block potential exploits targeting this vulnerability. This requires detailed knowledge of the vulnerability’s exploit vectors.
