CVE-2025-62259 is an authorization bypass vulnerability classified under CWE-863 affecting multiple versions of Liferay Portal and Liferay DXP, including 7.4.0 through 7.4.3.109 and 2023.Q3.1 through 2023.Q3.4, among others. The core issue is that the affected Liferay versions do not enforce email verification before granting access to certain APIs. This means that remote users, without any authentication or user interaction, can invoke APIs to access and modify portal content. The vulnerability arises from improper access control checks that fail to restrict API calls until the user’s email address is verified, allowing unauthorized content editing. 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 impact on confidentiality and integrity but no impact on availability. No public exploits have been reported yet, but the ease of exploitation and the ability to modify content remotely pose a significant risk. The vulnerability affects both supported and unsupported versions, complicating mitigation for organizations running legacy systems. Since Liferay Portal is widely used for enterprise web content management and digital experience platforms, unauthorized content changes could lead to misinformation, defacement, or further exploitation.

For European organizations, the impact includes unauthorized modification of web content, which can undermine data integrity, damage brand reputation, and potentially facilitate further attacks such as phishing or malware distribution through compromised content. Organizations relying on Liferay for customer-facing portals, intranets, or digital services may experience trust erosion if attackers manipulate displayed information. The vulnerability does not directly impact confidentiality or availability but compromises integrity and could disrupt business operations indirectly. Given the lack of authentication requirements, attackers can exploit this vulnerability remotely without user interaction, increasing the attack surface. Public sector entities, financial institutions, and large enterprises using Liferay in Europe are particularly at risk due to their reliance on accurate and secure content delivery. The absence of known exploits currently limits immediate widespread damage but also means organizations should proactively address the issue before exploitation occurs.

1. Apply official patches from Liferay as soon as they become available for all affected versions. 2. Until patches are released, implement network-level restrictions to limit API access to trusted IP ranges or VPNs. 3. Configure web application firewalls (WAFs) to detect and block unauthorized API calls that attempt to modify content without verified email status. 4. Review and harden API access controls by enforcing email verification or additional authentication mechanisms before allowing content edits. 5. Monitor logs for unusual API activity, especially from unauthenticated sources, and establish alerting for suspicious content modification attempts. 6. Conduct internal audits of Liferay configurations and user verification workflows to ensure no bypasses exist. 7. Educate administrators and developers about the vulnerability and encourage prompt remediation. 8. Consider isolating legacy or unsupported Liferay instances from public networks until they can be upgraded or patched.
