CVE-2025-62889 is a missing authorization vulnerability identified in the King Addons for Elementor plugin developed by KingAddons.com, affecting all versions up to and including 51.1.37. This vulnerability arises from incorrectly configured access control security levels, allowing attackers with low privileges (PR:L) to perform unauthorized actions remotely over the network (AV:N) without requiring user interaction (UI:N). The vulnerability impacts confidentiality, integrity, and availability at a high level (C:H/I:H/A:H), indicating that an attacker could potentially access sensitive data, modify content or configurations, and disrupt website functionality. The plugin is widely used as an extension to the popular Elementor page builder for WordPress, which is a common platform for building websites. The lack of proper authorization checks means that attackers can exploit this flaw to escalate privileges or perform administrative actions that should be restricted. Although no known exploits are currently reported in the wild, the high CVSS score of 8.8 reflects the serious risk posed by this vulnerability. The vulnerability was published on October 27, 2025, and was assigned by Patchstack. No patches or fixes are currently linked, indicating that organizations must be vigilant and prepare to apply updates once available. The vulnerability's network accessibility and lack of user interaction requirement make it particularly dangerous for internet-facing WordPress sites using this plugin.

European organizations using King Addons for Elementor are at risk of unauthorized access and control over their websites, which can lead to data breaches, defacement, or service disruption. This is especially critical for businesses relying on their websites for customer engagement, e-commerce, or sensitive data processing. The compromise of website integrity can damage brand reputation and lead to regulatory penalties under GDPR if personal data is exposed. Additionally, attackers could leverage compromised sites as footholds for further attacks within corporate networks. The high severity and network exploitability mean that even low-privileged users or automated attacks could trigger exploitation, increasing the risk profile. Organizations in sectors such as finance, healthcare, and government, which often use WordPress-based sites for public-facing portals, are particularly vulnerable. The absence of known exploits currently provides a window for proactive mitigation but also suggests that attackers may develop exploits soon given the high impact.

1. Monitor KingAddons.com and trusted security advisories closely for official patches addressing CVE-2025-62889 and apply them immediately upon release. 2. Until patches are available, restrict access to WordPress admin and plugin management interfaces using IP whitelisting or VPNs to limit exposure. 3. Implement strict role-based access controls within WordPress to minimize privileges granted to users, especially limiting plugin management capabilities. 4. Use Web Application Firewalls (WAFs) with custom rules to detect and block suspicious requests targeting the King Addons plugin endpoints. 5. Conduct regular security audits and vulnerability scans focused on WordPress plugins to detect unauthorized changes or suspicious activity. 6. Maintain comprehensive backups of website data and configurations to enable rapid recovery in case of compromise. 7. Educate site administrators on the risks of installing or updating plugins from unverified sources and encourage the use of security plugins that monitor for unauthorized changes. 8. Consider temporarily disabling or uninstalling the King Addons plugin if it is not critical to website functionality until a secure version is available.
