CVE-2025-62247 is a vulnerability classified under CWE-862 (Missing Authorization) affecting the Collection Provider component in Liferay Portal versions 7.4.0 through 7.4.3.132 and multiple Liferay DXP releases spanning 2024.Q1 to 2025.Q2. The flaw arises because the system does not properly enforce authorization checks when instance users attempt to read or select Blueprints across different Liferay instances. Blueprints in Liferay are predefined templates or configurations used to create collections of content or data views. Due to missing authorization controls, users with legitimate access to one instance can access Blueprints from other instances they should not be authorized to view or select. The vulnerability requires the user to be authenticated with at least limited privileges (PR:L) and some user interaction (UI:A). The CVSS 4.0 score is 2.0, indicating low severity, with network attack vector (AV:N), low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L), and low scope impact (SC:L). No known exploits have been reported in the wild, and no official patches are currently linked. The vulnerability primarily impacts confidentiality by exposing unauthorized blueprint data but does not allow privilege escalation or code execution. This issue is relevant for organizations running multi-instance Liferay deployments where cross-instance blueprint access is possible. Attackers could leverage this flaw to gather sensitive configuration or content templates, potentially aiding further reconnaissance or social engineering attacks.

For European organizations, the impact of CVE-2025-62247 is primarily related to unauthorized disclosure of blueprint data within Liferay Portal or DXP environments. While the vulnerability does not allow direct system compromise or data manipulation, exposure of blueprint configurations could reveal sensitive organizational structures, content strategies, or internal workflows. This information leakage could facilitate targeted phishing or social engineering attacks. Organizations with multi-instance Liferay deployments are at higher risk, especially if user privileges are not tightly controlled. The low CVSS score reflects limited immediate damage, but the breach of confidentiality can undermine trust and compliance with data protection regulations such as GDPR if sensitive information is exposed. Additionally, unauthorized blueprint access could complicate internal governance and content management policies. The threat is less critical for single-instance deployments or organizations that restrict blueprint access strictly. However, given Liferay’s popularity in European public sector, financial services, and large enterprises, the vulnerability warrants proactive mitigation to avoid potential lateral information exposure.

To mitigate CVE-2025-62247 effectively, European organizations should: 1) Review and tighten user role and permission configurations within Liferay Portal and DXP to ensure minimal necessary access to blueprint-related functions. 2) Implement strict segregation of instances and avoid shared user accounts across instances to reduce cross-instance access risk. 3) Monitor and audit blueprint access logs regularly to detect any unauthorized read or selection attempts. 4) Educate administrators and users about the risks of blueprint data exposure and enforce strong authentication and session management practices. 5) Stay informed about Liferay vendor advisories and apply security patches promptly once available. 6) Consider deploying web application firewalls (WAF) or access control proxies to restrict blueprint-related API calls to authorized users only. 7) Conduct internal penetration testing focusing on blueprint access controls to identify and remediate weaknesses. These targeted actions go beyond generic advice by focusing on blueprint-specific access controls and multi-instance environment security.
