CVE-2025-62999 is a vulnerability identified in the themezaa Litho Addons WordPress plugin, specifically versions up to and including 3.4. The root cause is missing authorization checks, which results in incorrectly configured access control security levels. This flaw allows attackers who have at least low-level privileges (PR:L) to exploit the plugin remotely (AV:N) without requiring user interaction (UI:N). The vulnerability impacts the confidentiality and integrity of affected systems, enabling unauthorized access or modification of data managed by the plugin. The CVSS 3.1 base score is 5.4, indicating a medium severity level. Although no known exploits are currently reported in the wild, the vulnerability poses a risk to websites using this plugin, especially those with multiple user roles or contributors. The lack of proper authorization means that users with limited permissions could perform actions beyond their intended scope, potentially leading to data leakage or unauthorized content changes. The plugin is commonly used in WordPress environments to enhance site functionality, making it a relevant target for attackers seeking to leverage privilege escalation vectors within web applications. The vulnerability was reserved in late October 2025 and published in December 2025, with no patch links currently available, indicating that remediation may still be pending or in progress.

For European organizations, the impact of CVE-2025-62999 can be significant, particularly for those relying on WordPress sites enhanced by the Litho Addons plugin. Unauthorized access or modification of site content can lead to data breaches, loss of customer trust, and potential regulatory non-compliance under GDPR if personal data is exposed. The integrity of website content is critical for brand reputation and operational continuity, especially for e-commerce, media, and public sector websites. Since the vulnerability requires only low privileges and no user interaction, insider threats or compromised low-level accounts could be leveraged to escalate privileges or manipulate site data. Although availability is not directly impacted, the indirect effects of data tampering or exposure could disrupt business operations. The medium severity rating suggests that while the threat is not critical, it should not be ignored, especially in environments with multiple contributors or complex access control requirements. Organizations with high web traffic or sensitive data hosted on WordPress platforms are at increased risk.

To mitigate CVE-2025-62999, European organizations should first inventory their WordPress installations to identify the presence and version of the Litho Addons plugin. Until an official patch is released, administrators should restrict plugin access to trusted users only and review user roles and permissions to ensure the principle of least privilege is enforced. Implementing Web Application Firewalls (WAF) with custom rules to detect and block suspicious requests targeting the plugin’s endpoints can reduce exploitation risk. Regularly monitoring logs for unusual activity related to the plugin is advised. Organizations should subscribe to vendor and security advisories for updates and apply patches promptly once available. Additionally, conducting security audits and penetration testing focused on access control mechanisms within WordPress plugins can help identify similar vulnerabilities. Employing multi-factor authentication (MFA) for administrative accounts and enforcing strong password policies further reduces the risk of account compromise that could be leveraged to exploit this vulnerability.
