Understanding the Drupal Entity Share Vulnerability
A recent security finding, identified as CVE-2025-13985, highlights a significant issue within the Drupal Entity Share module. This vulnerability centers around incorrect authorization, which could allow an attacker to bypass intended access controls. In simple terms, this means that the module might not properly check if a user has permission to view certain content, potentially leading to unauthorized access to information that should be protected. This type of flaw is often referred to as “forceful browsing,” where an attacker can access sensitive pages or data simply by guessing or directly navigating to their URLs, without proper authentication or authorization checks.
This vulnerability is particularly concerning for websites that rely on Entity Share to manage content distribution and access across different Drupal sites. It underscores the importance of keeping all your modules updated to maintain a strong security posture.
CVE Details
- Product Name: Drupal Entity Share
- Published: January 28, 2026
- Severity: Medium
- Status: Analyzed
Affected Products
The CVE-2025-13985 vulnerability impacts specific versions of the Drupal Entity Share module. If your website uses Entity Share, you are affected if your version is anywhere from 0.0.0 up to, but not including, version 3.13.0. This means any version older than 3.13.0 is vulnerable. It is crucial to check your installed version to determine your exposure to this risk.
Current Status
This vulnerability has been officially “Analyzed.” This status indicates that the details of the flaw have been reviewed and confirmed, and the scope of the issue is understood. While “Analyzed” confirms the vulnerability’s existence and characteristics, it also implies that the vendor has acknowledged the problem and is likely working on or has released a fix.
Severity Level
The vulnerability is classified with a “Medium” severity level, alongside a CVSS score of 5.3. A medium severity rating means that while the vulnerability is not immediately critical and unlikely to lead to complete system compromise without additional exploits, it can still pose a significant risk. Attackers could potentially gain access to sensitive data, alter content, or disrupt services if they successfully exploit this authorization flaw. For an attacker, this could involve gaining information they should not have access to, which might then be used in further, more sophisticated attacks.
Possible Solutions
The most direct and effective solution for the CVE-2025-13985 vulnerability is to upgrade your Drupal Entity Share module. The vulnerability specifically affects versions prior to 3.13.0. Therefore, it is highly recommended that all users update their Entity Share module to version 3.13.0 or a later, stable release as soon as possible. Keeping your Drupal core and contributed modules up-to-date is a fundamental practice in maintaining a secure website and mitigating potential risks.
