CVE-2025-58793 is a Stored Cross-Site Scripting (XSS) vulnerability classified under CWE-79, affecting the WPBean WPB Elementor Addons plugin for WordPress. This vulnerability arises from improper neutralization of input during web page generation, allowing malicious actors to inject and store arbitrary scripts within the plugin's data handling processes. When a victim accesses a page containing the malicious payload, the script executes in their browser context, potentially leading to session hijacking, defacement, unauthorized actions, or data theft. The affected versions include all versions up to 1.6, with no specific lower bound version identified. The vulnerability has a CVSS v3.1 base score of 6.5, indicating a medium severity level. The vector details (AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L) show that the attack can be performed remotely over the network with low attack complexity, requires privileges (likely contributor/editor level) and user interaction (victim must visit the malicious page). The scope is changed, meaning the vulnerability affects resources beyond the vulnerable component itself. Although no known exploits are currently reported in the wild, the nature of stored XSS makes it a significant risk for websites using this plugin, especially those with multiple users or visitors. Stored XSS can be leveraged to perform persistent attacks against site administrators or visitors, potentially compromising confidentiality, integrity, and availability of the affected WordPress sites.

For European organizations, the impact of this vulnerability can be substantial, particularly for businesses and institutions relying on WordPress websites enhanced with WPB Elementor Addons. Exploitation could lead to unauthorized access to user sessions, theft of sensitive information such as login credentials or personal data, and unauthorized actions performed on behalf of legitimate users. This can result in reputational damage, regulatory non-compliance (notably with GDPR), financial losses, and disruption of online services. Organizations in sectors such as e-commerce, government, education, and media, which often use WordPress for content management, are at heightened risk. The vulnerability's ability to affect the confidentiality, integrity, and availability of web applications means that attackers could deface websites, inject malicious content, or disrupt service availability, undermining trust and operational continuity.

To mitigate this vulnerability, European organizations should: 1) Immediately identify and inventory all WordPress sites using the WPB Elementor Addons plugin, especially versions up to 1.6. 2) Apply patches or updates as soon as they become available from the vendor; if no patch is currently available, consider temporarily disabling or removing the plugin to eliminate the attack surface. 3) Implement strict input validation and output encoding on all user-generated content fields to prevent injection of malicious scripts. 4) Employ Web Application Firewalls (WAFs) with rules targeting XSS payloads to provide an additional layer of defense. 5) Conduct regular security audits and penetration testing focusing on plugin vulnerabilities. 6) Educate site administrators and users about the risks of clicking on suspicious links and the importance of least privilege principles to limit the impact of compromised accounts. 7) Monitor logs and user activity for signs of exploitation attempts or unusual behavior. These steps go beyond generic advice by emphasizing immediate plugin inventory and removal if patches are unavailable, combined with layered defenses and user awareness.
