CVE-2025-3059 is a medium-severity vulnerability affecting the Drupal Profile Private module, impacting all versions of the module (denoted as *.*). The vulnerability is classified under CWE-200, which corresponds to information exposure. Specifically, this flaw allows an unauthenticated remote attacker to access certain private profile data that should otherwise be restricted. The CVSS v3.1 base score is 5.3, reflecting a medium impact primarily on confidentiality, with no impact on integrity or availability. The attack vector is network-based (AV:N), requiring no privileges (PR:N) and no user interaction (UI:N), making exploitation relatively straightforward if the vulnerable module is exposed. The scope is unchanged (S:U), meaning the vulnerability affects only the vulnerable component without impacting other system components. The vulnerability does not have any known exploits in the wild as of the publication date (March 31, 2025), and no patches have been released yet. The lack of patches and the broad version impact imply that all Drupal sites using the Profile Private module are potentially vulnerable to unauthorized data disclosure until remediation is applied. The technical details indicate that the vulnerability was reserved and published on the same date, suggesting recent discovery and disclosure. Given the nature of the vulnerability, it likely involves improper access control or failure to enforce privacy settings on user profile data within the module, leading to unintended data leakage over the network.

For European organizations, the primary impact of CVE-2025-3059 is the unauthorized disclosure of private user profile information hosted on Drupal websites utilizing the Profile Private module. This can lead to privacy violations, non-compliance with GDPR and other data protection regulations, reputational damage, and potential legal penalties. Organizations that rely on Drupal for customer portals, membership sites, or internal employee directories are particularly at risk. Although the vulnerability does not affect data integrity or availability, the exposure of sensitive personal data can facilitate further attacks such as social engineering, phishing, or identity theft. The ease of exploitation without authentication increases the risk profile, especially for publicly accessible Drupal sites. Since no known exploits exist yet, the immediate threat may be limited, but the window before patch availability requires proactive mitigation. The impact is more pronounced for sectors handling sensitive personal data, including healthcare, finance, education, and government services within Europe.

1. Immediate mitigation should include auditing all Drupal installations to identify the presence of the Profile Private module and assessing exposure levels. 2. Restrict public access to Drupal sites or specific endpoints serving profile data where feasible, using web application firewalls (WAFs) or access control lists (ACLs). 3. Implement strict network segmentation and IP whitelisting to limit access to trusted users only. 4. Monitor web server and application logs for unusual access patterns or data requests that could indicate exploitation attempts. 5. Until an official patch is released, consider disabling or uninstalling the Profile Private module if it is not critical to operations. 6. For sites where disabling is not feasible, apply custom access control rules or Drupal permissions to enforce stricter data visibility. 7. Prepare for rapid deployment of patches once available by maintaining an up-to-date inventory and testing environment. 8. Educate site administrators and developers about the vulnerability and encourage timely updates. 9. Review and enhance privacy policies and incident response plans to address potential data exposure incidents.
