CVE-2025-62999 identifies a missing authorization vulnerability in the themezaa Litho Addons WordPress plugin, specifically affecting versions up to 3.4. The vulnerability arises from incorrectly configured access control security levels, which fail to properly restrict user permissions for certain plugin functionalities. This misconfiguration can allow an attacker, potentially even without authentication, to perform unauthorized actions that should be limited to privileged users. The plugin is used to extend WordPress capabilities, and such unauthorized access could lead to data leakage, content manipulation, or further compromise of the hosting environment. No CVSS score has been assigned yet, and no public exploits have been reported, but the nature of missing authorization vulnerabilities typically allows relatively straightforward exploitation. The vulnerability was reserved in late October 2025 and published in December 2025, indicating recent discovery. The absence of patches at the time of publication suggests that users must implement manual mitigations or monitor for updates. The threat primarily affects WordPress sites using the Litho Addons plugin, which is popular among European web developers for site customization.

For European organizations, this vulnerability could lead to unauthorized access to sensitive website management functions or data, undermining confidentiality and integrity. Attackers exploiting this flaw might alter website content, inject malicious code, or exfiltrate data, potentially damaging brand reputation and customer trust. Given the widespread use of WordPress across Europe, especially in small to medium enterprises and digital agencies, the impact could be significant if exploited at scale. Additionally, compromised websites could serve as launchpads for further attacks within corporate networks or be used to distribute malware to visitors. The lack of authentication requirements lowers the barrier for exploitation, increasing risk. Regulatory implications under GDPR could arise if personal data is exposed or manipulated due to this vulnerability, leading to legal and financial consequences.

European organizations should immediately audit their WordPress installations to identify the use of themezaa Litho Addons plugin versions up to 3.4. Until an official patch is released, administrators should restrict plugin access to the minimum necessary user roles and disable any unnecessary features within the plugin. Implementing strict role-based access control (RBAC) and reviewing user permissions can reduce exposure. Monitoring web server and application logs for unusual access patterns or unauthorized actions related to the plugin is critical. Employing Web Application Firewalls (WAFs) with custom rules to block suspicious requests targeting plugin endpoints can provide temporary protection. Organizations should subscribe to vendor and security mailing lists to receive timely updates and apply patches promptly once available. Regular backups and incident response plans should be reviewed to prepare for potential exploitation scenarios.
