CVE-2025-62889 is a security vulnerability identified in the King Addons for Elementor plugin developed by KingAddons.com, affecting all versions up to and including 51.1.37. The vulnerability arises from missing authorization checks within the plugin's access control mechanisms, allowing attackers to bypass security restrictions that should prevent unauthorized users from performing privileged actions. This type of vulnerability typically occurs when the plugin fails to verify whether a user has the necessary permissions before executing sensitive operations, such as modifying plugin settings or injecting content. Since King Addons is a popular extension for the Elementor page builder on WordPress, widely used to enhance website functionality and design, exploitation of this flaw could enable attackers to manipulate website content, inject malicious code, or escalate privileges within the WordPress environment. Although no public exploits or active attacks have been reported yet, the vulnerability's presence in a widely deployed plugin makes it a significant risk. The lack of a CVSS score indicates that the vulnerability has not yet been fully assessed, but the nature of missing authorization typically leads to high-impact consequences. The vulnerability was reserved and published in late October 2025 by Patchstack, a known vulnerability aggregator, but no patches or fixes have been linked at this time, suggesting that users must remain vigilant and monitor for updates. The absence of authentication requirements for exploitation is not explicitly stated, but missing authorization often implies that an attacker with some level of access (e.g., a subscriber or contributor role) could escalate privileges or perform unauthorized actions. This vulnerability primarily threatens the confidentiality and integrity of affected systems by enabling unauthorized access and potential content manipulation, which could also lead to reputational damage and further compromise if leveraged for malware distribution or phishing.

For European organizations, the impact of CVE-2025-62889 can be significant, especially for those relying on WordPress websites enhanced with the King Addons for Elementor plugin. Unauthorized access due to missing authorization can lead to website defacement, injection of malicious scripts, data leakage, or unauthorized administrative actions. This can disrupt business operations, damage brand reputation, and expose sensitive customer or organizational data. Given the widespread use of WordPress in Europe for corporate, governmental, and e-commerce websites, exploitation could affect a broad range of sectors including finance, retail, public administration, and media. The vulnerability could also serve as a foothold for further attacks within the network if attackers gain administrative control over the website. Additionally, GDPR compliance implications arise if personal data is compromised, potentially leading to regulatory penalties. The absence of known exploits provides a window for proactive mitigation, but the risk remains elevated due to the plugin's popularity and the critical nature of authorization controls in web applications.

1. Monitor official KingAddons.com channels and trusted vulnerability databases for the release of security patches addressing CVE-2025-62889 and apply them immediately upon availability. 2. In the interim, restrict access to WordPress user roles that can manage or configure the King Addons plugin to only the most trusted administrators. 3. Audit current user permissions within WordPress to ensure that no unnecessary privileges are granted, especially to lower-tier roles such as contributors or subscribers. 4. Implement Web Application Firewall (WAF) rules to detect and block suspicious requests targeting plugin management endpoints. 5. Regularly review and harden WordPress security settings, including disabling plugin and theme editor capabilities for non-admin users. 6. Conduct security awareness training for site administrators about the risks of unauthorized access and the importance of timely patching. 7. Consider temporarily disabling or removing the King Addons plugin if it is not critical to website functionality until a patch is available. 8. Employ website integrity monitoring tools to detect unauthorized changes or injections promptly. 9. Maintain regular backups of website data and configurations to enable rapid recovery in case of compromise. These steps go beyond generic advice by focusing on access control tightening, proactive monitoring, and contingency planning specific to the nature of this missing authorization vulnerability.
