CVE-2025-62245 identifies a Cross-Site Request Forgery (CSRF) vulnerability in Liferay Portal and Liferay DXP versions ranging from 7.4.1 to 7.4.3.112 and multiple 2023 Q3 and Q4 releases. CSRF vulnerabilities allow attackers to induce authenticated users to perform unwanted actions on web applications without their consent. In this case, the vulnerability permits remote attackers to add and edit publication comments on the portal by exploiting the lack of proper CSRF protections. The vulnerability does not require any privileges or prior authentication, but the victim must be logged into the vulnerable portal and visit a maliciously crafted webpage or link. The CVSS 4.0 score is 5.1 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, but requiring user interaction. The impact primarily affects the integrity of portal content, as unauthorized comment additions or edits can lead to misinformation, defacement, or social engineering setups. No known public exploits or patches are currently available, but the vulnerability has been publicly disclosed and assigned a CVE ID. The lack of anti-CSRF tokens or insufficient validation of state-changing requests in the affected Liferay versions is the root cause. This vulnerability is significant for organizations relying on Liferay Portal for content management and collaboration, as it undermines trust in published content and may facilitate further attacks through social engineering or misinformation.

For European organizations, the primary impact is on the integrity of content hosted on Liferay Portal instances. Unauthorized addition or modification of publication comments can lead to misinformation, reputational damage, and potential facilitation of phishing or social engineering attacks targeting employees or customers. Organizations in sectors such as government, education, and enterprises using Liferay for internal or external collaboration may face operational disruptions or loss of stakeholder trust. Although confidentiality and availability are not directly impacted, the manipulation of content can indirectly affect decision-making and user confidence. The ease of exploitation—requiring only that a logged-in user visits a malicious page—raises the risk profile, especially in environments with high user interaction and external access. The absence of known exploits in the wild reduces immediate risk but does not eliminate the threat, as attackers may develop exploits following public disclosure. European organizations with public-facing portals or those allowing broad user comment privileges are particularly vulnerable to reputational and operational impacts.

Organizations should prioritize applying official patches or updates from Liferay once released to address this CSRF vulnerability. In the interim, implement or verify the presence of anti-CSRF tokens on all state-changing requests, especially those related to comment addition and editing. Restrict comment functionalities to authenticated and authorized users with minimal privileges necessary. Employ web application firewalls (WAFs) with rules to detect and block suspicious CSRF patterns or anomalous comment submissions. Educate users about the risks of clicking on unsolicited links or visiting untrusted websites while logged into corporate portals. Conduct regular security assessments and penetration tests focusing on CSRF and other web vulnerabilities in Liferay deployments. Monitor portal logs for unusual comment activity or patterns indicative of automated or unauthorized changes. Consider disabling comment features temporarily if they are not critical to operations until patches are applied. Finally, maintain an incident response plan to quickly address any detected exploitation attempts.
