CVE-2025-43825 is a vulnerability classified under CWE-201 (Insertion of Sensitive Information Into Sent Data) affecting Liferay Portal versions 7.4.0 through 7.4.3.132 and a broad range of Liferay DXP releases from 2023.Q3.1 through 2025.Q1.4. The issue arises from the improper handling of sensitive user data within Freemarker templates used by the portal. Freemarker is a widely used Java-based template engine that renders dynamic content. In this case, sensitive information that should remain confidential is inadvertently included in the rendered output, potentially exposing it to unauthorized actors. The vulnerability allows an attacker, who may have some level of privileges (PR:H) and requires user interaction (UI:A), to access and render confidential information that should be restricted. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no privileges required (PR:H indicates high privileges but CVSS vector shows PR:H which means privileges required but high), user interaction required, and low impact on confidentiality (VC:L), with no impact on integrity or availability. Although no exploits are currently known in the wild, the vulnerability poses a risk of sensitive data leakage, which could include personal identifiable information or business-critical data. The vulnerability affects a wide range of Liferay DXP quarterly releases and the 7.4 GA branch, indicating a broad attack surface for organizations using these versions. The lack of available patches at the time of publication necessitates immediate attention to configuration and access controls to mitigate risk.

For European organizations, the impact of CVE-2025-43825 primarily concerns the confidentiality of sensitive data processed or stored within Liferay Portal and DXP environments. Many enterprises, government agencies, and service providers in Europe rely on Liferay for web content management and digital experience platforms, often handling personal data subject to GDPR regulations. Unauthorized disclosure of such data could lead to regulatory penalties, reputational damage, and loss of customer trust. The vulnerability could be exploited to leak sensitive user information, potentially including personal identifiable information (PII), internal business data, or credentials if embedded in templates. This risk is heightened in sectors such as finance, healthcare, and public administration, where data sensitivity is paramount. Additionally, the requirement for some privileges and user interaction limits the attack vector but does not eliminate risk, especially in environments with multiple users or where social engineering could be used. The medium severity rating suggests moderate urgency but should not be underestimated given the regulatory and operational impacts. Organizations failing to address this vulnerability may face data breaches and compliance violations.

1. Apply official patches or updates from Liferay as soon as they become available to address CVE-2025-43825. 2. Conduct a thorough audit of all Freemarker templates used within the portal environment to identify any that may expose sensitive information. 3. Restrict access to sensitive data within templates by implementing strict data access controls and minimizing the data passed to templates. 4. Limit user privileges to the minimum necessary to reduce the risk of exploitation by users with elevated rights. 5. Implement monitoring and logging to detect unusual access patterns or attempts to render sensitive data. 6. Educate users and administrators about the risks of social engineering that could facilitate exploitation requiring user interaction. 7. Consider deploying web application firewalls (WAF) with custom rules to detect and block suspicious template rendering requests. 8. Review and enhance overall data governance policies to ensure sensitive data is classified and handled appropriately within portal applications. 9. If immediate patching is not possible, isolate or restrict access to affected Liferay instances to trusted networks and users only.
