CVE-2025-62259 is an authorization vulnerability identified in Liferay Portal versions 7.4.0 through 7.4.3.109 and several Liferay DXP versions including 2023.Q3.1 through 2023.Q3.4, 7.4 GA through update 92, and 7.3 GA through update 35. The core issue is that the portal does not enforce email verification prior to granting access to certain APIs, which allows remote attackers to access and edit content without proper authorization. This vulnerability is classified under CWE-863 (Incorrect Authorization), indicating that the system fails to restrict access to resources based on user privileges. The flaw permits unauthenticated users to interact with APIs that should be limited to verified users, potentially leading to unauthorized content modification. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N) indicates network attack vector, low attack complexity, no privileges or user interaction required, and limited confidentiality and integrity impact without availability impact. No patches or exploits are currently documented, but the vulnerability is publicly disclosed and should be addressed promptly. The vulnerability affects both supported and older unsupported versions, increasing the risk for organizations that have not updated their Liferay installations. The lack of email verification enforcement before API access is a critical design oversight that undermines the portal’s security model, potentially allowing attackers to manipulate content remotely and anonymously.

For European organizations, this vulnerability poses a significant risk to the confidentiality and integrity of content managed through Liferay Portal and DXP platforms. Unauthorized access to APIs without email verification can lead to content tampering, defacement, or injection of malicious data, which can damage organizational reputation and trust. Sectors such as government, finance, education, and healthcare that rely on Liferay for content management and digital services are particularly vulnerable. The impact includes potential data integrity loss, unauthorized disclosure of sensitive information if content is exposed or altered, and disruption of business processes relying on accurate portal content. Given the ease of exploitation (no authentication or user interaction required), attackers can automate attacks at scale, increasing the threat surface. While availability is not directly impacted, the indirect effects of content manipulation can lead to service disruptions or compliance violations under regulations like GDPR. Organizations with legacy or unsupported Liferay versions face elevated risks due to lack of vendor patches and mitigations.

European organizations should immediately audit their Liferay Portal and DXP deployments to identify affected versions. Applying vendor patches or updates that enforce email verification prior to API access is the most effective mitigation. If patches are not yet available, organizations should implement compensating controls such as restricting API access via network-level controls (firewalls, API gateways) to trusted IP ranges or authenticated users only. Enforce strict access control policies on APIs, including multi-factor authentication and role-based access controls. Monitor API usage logs for anomalous or unauthorized access patterns indicative of exploitation attempts. Disable or limit API endpoints that allow content editing until the vulnerability is remediated. Conduct regular security assessments and penetration testing focused on API authorization controls. Educate administrators and developers about the importance of email verification and proper authorization checks in portal security. Finally, maintain an incident response plan to quickly address any detected exploitation or content tampering incidents.
