CVE-2025-62090 identifies a Missing Authorization vulnerability in the Jegstudio Gutenverse News – Advanced News Magazine Blog Gutenberg Blocks Addons plugin for WordPress, specifically versions up to 3.0.2. The vulnerability arises from improperly configured access control mechanisms within the plugin, allowing attackers to perform actions without proper authorization. This could include unauthorized content modification, data leakage, or manipulation of the blog's news blocks. Since the plugin extends WordPress's Gutenberg editor with advanced news magazine features, exploitation could impact the integrity and confidentiality of published content. The vulnerability does not require user authentication, increasing the risk profile. Although no public exploits have been reported yet, the flaw is publicly disclosed and could be targeted by attackers once weaponized. The lack of a CVSS score necessitates an assessment based on the nature of the flaw: missing authorization typically leads to high severity due to the direct bypass of security controls. The plugin is used primarily in WordPress environments focused on news and magazine content, which are common in European media sectors. The vulnerability was reserved in October 2025 and published in December 2025, indicating recent discovery and disclosure. No patches or mitigations have been officially released at the time of this report, emphasizing the need for proactive defense measures.

For European organizations, especially those operating news, magazine, or media websites using WordPress with the Gutenverse News plugin, this vulnerability poses a significant risk. Unauthorized access could allow attackers to alter published content, inject malicious information, or exfiltrate sensitive editorial data, damaging reputation and trust. The integrity of news content is critical in Europe due to regulatory scrutiny and the importance of media reliability. Additionally, unauthorized changes could lead to misinformation or disinformation campaigns. The absence of authentication requirements means attackers can exploit the vulnerability remotely without credentials, increasing the attack surface. This could also facilitate further attacks such as privilege escalation or lateral movement within the affected systems. The impact extends to compliance risks under GDPR if personal data is exposed or manipulated. Overall, the vulnerability threatens confidentiality, integrity, and availability of content management systems in affected organizations.

Immediate mitigation steps include restricting access to the WordPress admin interface and the Gutenverse News plugin settings to trusted users only, ideally through IP whitelisting or VPN access. Organizations should monitor logs for unusual activity related to the plugin, such as unexpected content changes or unauthorized API calls. Until an official patch is released, consider disabling or uninstalling the Gutenverse News plugin if feasible, especially in high-risk environments. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting the plugin’s endpoints. Conduct a thorough review of user roles and permissions within WordPress to ensure least privilege principles are enforced. Regularly back up website data to enable recovery in case of compromise. Stay informed on vendor updates and apply patches promptly once available. Additionally, perform security audits on other installed plugins to identify similar authorization issues.
