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 from 2024.Q1 through 2025.Q2. The flaw arises because the system fails to properly enforce authorization checks when instance users attempt to read or select Blueprints via Collection Providers across instances. Blueprints in Liferay are templates or configurations used to create content or site structures. This missing authorization allows users with limited privileges within one instance to access Blueprints they should not be able to view or select, potentially exposing sensitive configuration or content templates. The vulnerability requires the user to be authenticated with at least limited privileges and involves user interaction to exploit. The CVSS 4.0 base score is 2.0, indicating low severity, reflecting the limited scope and impact. The vulnerability primarily compromises confidentiality by unauthorized data exposure but does not directly affect system integrity or availability. No public exploits or active exploitation have been reported to date. The issue affects a broad range of Liferay DXP versions, indicating that many organizations running these versions could be vulnerable if they have multi-instance setups or shared environments. The lack of patch links suggests that fixes may be forthcoming or that mitigation relies on configuration changes. Organizations should review their Liferay instance configurations and user permission models to prevent unauthorized blueprint access.

For European organizations, the primary impact of CVE-2025-62247 is unauthorized disclosure of blueprint configurations within Liferay Portal or DXP environments. This could lead to leakage of sensitive site templates or configuration data, which might be leveraged for further reconnaissance or social engineering attacks. While the vulnerability does not allow privilege escalation or direct system compromise, the exposure of internal blueprint data could undermine confidentiality and trust in affected portals. Organizations using Liferay for critical services, such as government portals, financial institutions, or healthcare providers, may face reputational damage or compliance issues if sensitive blueprint information is exposed. The impact is mitigated by the requirement for authenticated users with some privileges and user interaction, limiting the attack surface primarily to insiders or compromised accounts. However, in multi-tenant or multi-instance deployments common in large enterprises or service providers, the risk of cross-instance data leakage is more pronounced. Overall, the vulnerability poses a moderate risk to confidentiality but low risk to integrity and availability.

1. Conduct a thorough audit of user roles and permissions within Liferay Portal and DXP instances to ensure that users only have access to necessary Blueprints and Collection Providers. 2. Implement strict access control policies and segregation between instances to prevent unauthorized cross-instance access. 3. Monitor user activities related to blueprint access and selection to detect anomalous behavior indicative of exploitation attempts. 4. Apply any vendor-provided patches or updates as soon as they become available to address the missing authorization flaw. 5. If patches are not yet available, consider disabling or restricting the Collection Provider component or blueprint sharing features where feasible until a fix is deployed. 6. Educate users about the risks of unauthorized blueprint access and enforce strong authentication mechanisms to reduce the risk of compromised accounts. 7. Regularly review and update security configurations in multi-instance environments to minimize exposure. 8. Engage with Liferay support or security advisories to stay informed about remediation progress and best practices.
