Technical Analysis

CVE-2025-48013 is a security vulnerability identified in the Drupal Quick Node Block module, specifically affecting versions prior to 2.0.0, including version 0.0.0. The vulnerability is classified as CWE-862, which corresponds to Missing Authorization. This flaw allows an attacker to perform forceful browsing, meaning unauthorized users can access resources or pages that should be restricted. The vulnerability arises because the module fails to properly enforce authorization checks before granting access to certain nodes or blocks, allowing unauthenticated or unauthorized users to view content they should not have access to. The CVSS v3.1 base score is 5.3 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:N), no user interaction needed (UI:N), unchanged scope (S:U), limited confidentiality impact (C:L), and no impact on integrity or availability (I:N/A:N). There are no known exploits in the wild at the time of publication, and no patches have been linked yet. This vulnerability could be exploited remotely without authentication or user interaction, making it a concern for any Drupal site using the affected Quick Node Block versions. The issue primarily impacts confidentiality by allowing unauthorized data disclosure but does not affect data integrity or system availability.

Potential Impact

For European organizations, this vulnerability poses a risk of unauthorized disclosure of potentially sensitive or restricted content hosted on Drupal sites using the Quick Node Block module. Organizations in sectors such as government, healthcare, finance, and education, which often use Drupal for content management, could face data confidentiality breaches. Although the vulnerability does not allow modification or deletion of data, unauthorized access to internal or confidential information could lead to reputational damage, regulatory non-compliance (e.g., GDPR violations), and potential legal consequences. Since the vulnerability requires no authentication and can be exploited remotely, attackers could automate scanning and exploitation attempts, increasing the risk of widespread unauthorized data exposure. The medium severity rating suggests the impact is significant but not critical; however, the ease of exploitation and the potential sensitivity of exposed data make timely remediation important.

Mitigation Recommendations

European organizations should take immediate steps to mitigate this vulnerability beyond generic advice. First, they should identify all Drupal instances using the Quick Node Block module and verify the version in use. Since no official patches are linked yet, organizations should monitor Drupal security advisories closely for updates or patches addressing CVE-2025-48013. In the interim, organizations can implement access control restrictions at the web server or application firewall level to limit access to sensitive nodes or blocks, effectively compensating for the missing authorization in the module. Conducting a thorough audit of content permissions and restricting public access to sensitive content can reduce exposure. Additionally, organizations should enable detailed logging and monitoring to detect unusual access patterns indicative of forceful browsing attempts. Applying the principle of least privilege to user roles and reviewing Drupal permissions can further reduce risk. Finally, organizations should plan for rapid deployment of patches once available and consider engaging with Drupal security experts to assess and remediate the vulnerability in their environments.
