CVE-2025-62275 is a security vulnerability classified under CWE-863 (Incorrect Authorization) affecting multiple versions of Liferay Portal and Liferay DXP. The vulnerability arises because the affected versions do not properly enforce permission checks on images embedded within blog entries. As a result, remote attackers can craft URLs to directly access these images without any authentication or authorization, bypassing intended access controls. This flaw impacts Liferay Portal versions 7.4.0 through 7.4.3.111 and Liferay DXP versions 2023.Q4.0 through 2023.Q4.10, 2023.Q3.1 through 2023.Q3.10, and 7.4 GA through update 92, including some older unsupported versions. The vulnerability is exploitable remotely over the network without requiring user interaction or privileges, making it relatively easy to exploit. The CVSS 4.0 base score is 6.9, indicating medium severity, primarily due to the confidentiality impact (limited disclosure of images) without affecting integrity or availability. No known exploits have been reported in the wild as of the publication date. The vulnerability could lead to unauthorized disclosure of potentially sensitive images embedded in blogs, which may contain confidential or proprietary information. The lack of proper authorization checks represents a design weakness in the access control mechanisms of Liferay's blog image handling. Since Liferay Portal and DXP are widely used enterprise content management platforms, this vulnerability could affect organizations relying on these products for internal or external content publishing. The absence of vendor patches at the time of reporting necessitates immediate attention to mitigate exposure risks through compensating controls.

The primary impact of CVE-2025-62275 is unauthorized disclosure of images embedded in blog entries within Liferay Portal and DXP environments. For European organizations, this could lead to leakage of sensitive or confidential visual information, potentially exposing internal communications, intellectual property, or personal data. While the vulnerability does not affect data integrity or system availability, the confidentiality breach could have regulatory implications under GDPR if personal data is involved. Organizations in sectors such as government, finance, healthcare, and critical infrastructure that use Liferay for content management may face reputational damage and compliance risks. The ease of exploitation without authentication increases the risk profile, especially for publicly accessible Liferay instances. However, the impact is somewhat limited by the scope of affected content (images in blogs) and the absence of known active exploitation. Nonetheless, attackers could use this vulnerability as part of broader reconnaissance or data exfiltration campaigns. European entities with extensive use of Liferay Portal or DXP should consider this vulnerability a moderate risk that requires timely mitigation to prevent unauthorized data exposure.

1. Apply official patches from Liferay as soon as they become available to address the authorization flaw directly. 2. Until patches are released, restrict public access to blog entries containing sensitive images by implementing network-level access controls such as IP whitelisting or VPN requirements. 3. Review and tighten permissions on blog content and associated media libraries to ensure only authorized users can view sensitive images. 4. Implement web application firewalls (WAFs) with custom rules to detect and block suspicious URL patterns attempting to access blog images directly. 5. Monitor web server and application logs for unusual access patterns or repeated requests to blog image URLs that could indicate exploitation attempts. 6. Educate content creators and administrators about the risks of embedding sensitive images in publicly accessible blogs and encourage use of secure storage alternatives. 7. Conduct regular security assessments and penetration testing focused on access control mechanisms in Liferay environments. 8. Consider disabling or limiting the blog feature if it is not essential to reduce the attack surface. These measures go beyond generic advice by focusing on compensating controls and monitoring strategies tailored to the specific vulnerability context.
