Understanding the Drupal Access Code Brute Force Vulnerability (CVE-2025-10928)
A security flaw has been identified in the Access code module for Drupal, a popular content management system. This vulnerability, tracked as CVE-2025-10928, is related to an “Improper Restriction of Excessive Authentication Attempts,” which essentially means it makes systems vulnerable to brute-force attacks. In simple terms, this weakness could allow an attacker to repeatedly guess authentication codes or credentials without proper blocking, potentially gaining unauthorized access.
It’s crucial for website administrators and developers using this module to understand the potential risks and take appropriate steps to secure their Drupal installations.
CVE Details
This vulnerability affects the Access code module for Drupal. It was publicly disclosed on October 30, 2025, and its severity is rated as Medium. The status of this vulnerability is currently listed as Analyzed.
Affected Products
The specific component impacted is the Access code project’s Access code module for Drupal. Users running versions of this module from 0.0.0 before 2.0.5 are at risk. If your Drupal site uses the Access code module within this version range, it is considered vulnerable.
Current Status
The vulnerability has been thoroughly Analyzed. This means security experts have investigated the issue, confirmed its existence, and understood its nature. While the vulnerability is known, proactive measures from users are still required to mitigate the risk.
Severity Level
CVE-2025-10928 has been assigned a Medium severity rating. A medium severity indicates that while the vulnerability could be exploited, it might require specific conditions or be less straightforward to execute compared to high-severity flaws. However, successful exploitation of a brute-force vulnerability can still lead to unauthorized access, data breaches, or denial of service, making it a significant concern that should not be ignored.

Administrators should:
- Check their current Access code module version.
- Monitor the official Drupal security advisories and the Access code module project page for specific patch releases and update instructions.
- Implement strong password policies and consider enabling multi-factor authentication where possible, as general security best practices against brute-force attacks.
Always back up your Drupal site before performing any updates to ensure data integrity.
