CVE-2025-62258 is a Cross-Site Request Forgery (CSRF) vulnerability identified in the Headless API component of Liferay Portal versions 7.4.0 through 7.4.3.107, Liferay DXP 2023.Q3.1 through 2023.Q3.4, and earlier supported versions including 7.4 GA through update 92 and 7.3 GA through update 35. The vulnerability arises because the Headless API does not adequately verify the origin of requests, allowing an attacker to craft malicious requests that execute arbitrary API calls via the 'endpoint' parameter. Since the vulnerability does not require authentication (AV:N/PR:N) but does require user interaction (UI:A), an attacker could trick an authenticated user into submitting a malicious request, thereby executing unauthorized actions on the server. The CVSS 4.0 score of 7 (high) reflects the ease of exploitation combined with the potential for significant impact on integrity and availability of the system. The vulnerability affects the confidentiality of data to a lesser extent (VC:L). No patches were listed at the time of publication, and no known exploits have been reported in the wild. The flaw is categorized under CWE-352, which is a common web security weakness related to CSRF attacks. Liferay Portal is widely used in enterprise environments for content management and digital experience platforms, making this vulnerability a critical concern for organizations relying on these systems.

For European organizations, the impact of CVE-2025-62258 can be substantial. Liferay Portal is commonly used in government, education, and large enterprises across Europe for managing digital content and services. Successful exploitation could allow attackers to perform unauthorized actions such as modifying content, changing configurations, or triggering workflows without the user's consent. This can lead to data integrity issues, service disruptions, and potential compliance violations under regulations like GDPR if personal data is affected. The vulnerability's ability to be exploited remotely without authentication increases the attack surface significantly. Organizations with exposed Liferay portals or insufficient network segmentation are particularly vulnerable. The requirement for user interaction means phishing or social engineering campaigns could be leveraged to facilitate attacks. The absence of known exploits currently provides a window for proactive mitigation, but the high severity score demands urgent attention to prevent future exploitation.

1. Apply official patches and updates from Liferay as soon as they become available to address CVE-2025-62258. 2. Implement robust anti-CSRF tokens in all Headless API endpoints to validate the origin and intent of requests. 3. Restrict access to the Headless API by enforcing strict network-level controls such as IP whitelisting and VPN-only access. 4. Employ Content Security Policy (CSP) headers and SameSite cookie attributes to reduce the risk of CSRF via browser-based attacks. 5. Conduct user awareness training to recognize and avoid phishing attempts that could trigger malicious requests. 6. Review and minimize user privileges to limit the potential impact of compromised accounts. 7. Monitor logs for unusual API activity that could indicate exploitation attempts. 8. Consider deploying Web Application Firewalls (WAF) with custom rules to detect and block suspicious Headless API calls. 9. Regularly audit and test the security posture of Liferay deployments, including penetration testing focused on API security.
