CVE-2025-62275 is a security vulnerability classified under CWE-863 (Incorrect Authorization) affecting Liferay Portal versions 7.4.0 through 7.4.3.111 and multiple Liferay DXP 2023 releases (Q3 and Q4 updates). The vulnerability arises because the portal does not enforce permission checks on images embedded within blog entries. This flaw allows remote attackers to access images by crafting specific URLs, bypassing intended access controls. The vulnerability requires no authentication or user interaction, making it remotely exploitable over the network. The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N) indicates that the attack vector is network-based, with low attack complexity, no privileges or user interaction required, and limited impact on confidentiality (partial exposure of images), with no impact on integrity or availability. While no public exploits have been reported, the exposure of images could lead to unauthorized disclosure of sensitive or confidential information contained in blog media. Liferay Portal and DXP are widely used enterprise content management and collaboration platforms, often deployed in corporate intranets and public-facing websites. The vulnerability affects multiple versions, including some older unsupported releases, emphasizing the need for patching or mitigation. The lack of patch links suggests that fixes may be pending or that users should monitor Liferay advisories closely. This vulnerability highlights the importance of strict access control enforcement on all content types, including embedded media, within web applications.

For European organizations, the primary impact of CVE-2025-62275 is unauthorized disclosure of images embedded in blog entries, which could contain sensitive corporate, personal, or strategic information. This exposure could lead to privacy violations, intellectual property leakage, or reputational damage if confidential images are accessed by unauthorized parties. Since the vulnerability does not affect integrity or availability, it is less likely to cause system disruption or data tampering. However, the ease of exploitation without authentication increases the risk surface, especially for publicly accessible Liferay portals. Organizations using Liferay for internal collaboration or external communications should be aware that attackers could harvest images without detection if access logs are not monitored. The medium severity rating reflects a moderate risk level, but the actual impact depends on the sensitivity of the exposed images and the deployment context. European entities in regulated sectors such as finance, healthcare, or government may face compliance risks if personal or sensitive data is exposed. Additionally, attackers could use the information gained from images for social engineering or further targeted attacks.

1. Monitor Liferay's official security advisories and apply patches promptly once available for the affected versions. 2. Until patches are released, restrict access to blog entries and their embedded images by configuring web server or application-level access controls, such as IP whitelisting or VPN-only access for sensitive content. 3. Implement URL filtering or web application firewall (WAF) rules to detect and block suspicious requests attempting to access blog images via crafted URLs. 4. Review and audit blog content to identify and remove sensitive images that should not be publicly accessible. 5. Enable detailed logging and monitoring of access to blog images to detect unusual or unauthorized access patterns. 6. Educate content creators and administrators about the importance of classifying and protecting sensitive media within the portal. 7. Consider isolating or segregating the blog service or media storage to minimize exposure in case of exploitation. 8. Conduct regular security assessments and penetration testing focused on access control enforcement in Liferay deployments.
