CVE-2025-62090 identifies a missing authorization vulnerability in the Jegstudio Gutenverse News plugin, which is a WordPress addon providing advanced magazine-style Gutenberg blocks for news blogs. The vulnerability arises from incorrectly configured access control mechanisms, allowing authenticated users with low privileges to perform actions beyond their authorization scope. Specifically, the flaw permits such users to modify or manipulate content or plugin settings without proper permission checks, thereby compromising data integrity. The vulnerability affects all versions up to and including 3.0.2. The CVSS 3.1 base score is 6.5 (medium), reflecting network attack vector, low attack complexity, requiring privileges but no user interaction, and impacting integrity only. No public exploits have been reported yet. The issue is significant because WordPress is widely used across Europe, and plugins like Gutenverse News are popular for media and news websites. Attackers exploiting this vulnerability could deface websites, inject misleading content, or disrupt editorial workflows. The lack of confidentiality or availability impact reduces the overall severity, but the integrity impact remains critical for content authenticity. The vulnerability was reserved in October 2025 and published in December 2025, with no patch links currently available, indicating that mitigation may rely on vendor updates or temporary access restrictions.

For European organizations, particularly media outlets, news agencies, and content publishers using WordPress with the Gutenverse News plugin, this vulnerability poses a risk of unauthorized content modification. Such tampering can damage brand reputation, spread misinformation, or disrupt editorial processes. Since the vulnerability requires only low-level authenticated access, insider threats or compromised user accounts could be leveraged to exploit it. The integrity compromise could also affect trustworthiness of published information, which is critical in the European context where misinformation is a sensitive issue. Although availability and confidentiality are not directly impacted, the potential for content defacement or unauthorized changes can lead to operational disruptions and loss of audience trust. Organizations with strict regulatory compliance requirements around content integrity (e.g., media regulations in Germany or France) may face legal or compliance consequences if exploited.

1. Monitor for vendor updates and apply patches for the Gutenverse News plugin promptly once released. 2. Restrict plugin management and content editing permissions strictly to trusted, necessary users only; review user roles and capabilities regularly. 3. Implement multi-factor authentication (MFA) for all WordPress user accounts to reduce risk of account compromise. 4. Employ web application firewalls (WAFs) with rules to detect and block suspicious requests targeting plugin endpoints. 5. Conduct regular audits of user activities and content changes to detect unauthorized modifications early. 6. Consider temporarily disabling or removing the Gutenverse News plugin if patching is delayed and risk is deemed unacceptable. 7. Educate content editors and administrators about the risk and signs of unauthorized changes. 8. Use WordPress security plugins that can enforce stricter access controls and monitor plugin vulnerabilities.
