CVE-2025-6687 is a stored Cross-Site Scripting (XSS) vulnerability affecting the Magic Buttons for Elementor WordPress plugin developed by rexdot. This vulnerability arises due to improper neutralization of input during web page generation (CWE-79). Specifically, the plugin's magic-button shortcode fails to sufficiently sanitize and escape user-supplied attributes, allowing authenticated users with contributor-level privileges or higher to inject arbitrary JavaScript code into pages. When other users access these compromised pages, the injected scripts execute in their browsers. The vulnerability affects all versions up to and including version 1.0 of the plugin. The CVSS v3.1 base score is 6.4, indicating a medium severity level. The vector string (AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N) shows that the attack can be performed remotely over the network with low attack complexity, requires privileges (contributor or higher), does not require user interaction, and impacts confidentiality and integrity with a changed scope. No known exploits are currently reported in the wild, and no official patches have been linked yet. This vulnerability is significant because stored XSS can lead to session hijacking, privilege escalation, defacement, or distribution of malware, especially within WordPress environments that are widely used for content management. The requirement for contributor-level access limits the attack surface to users who can create or edit content but do not have full administrative rights, which is common in multi-author WordPress sites. The scope change indicates that the vulnerability affects resources beyond the initially vulnerable component, potentially impacting other parts of the site or user sessions.

For European organizations, this vulnerability poses a moderate risk, particularly for those relying on WordPress sites with the Magic Buttons for Elementor plugin installed. Stored XSS can compromise the confidentiality of user data by stealing session cookies or credentials, and integrity by allowing attackers to manipulate site content or inject malicious payloads. This can lead to reputational damage, data breaches, and regulatory non-compliance under GDPR if personal data is exposed. Since contributor-level access is required, insider threats or compromised contributor accounts could be leveraged to exploit this vulnerability. Organizations with multi-user WordPress environments, such as media companies, educational institutions, and e-commerce platforms, are especially at risk. The lack of user interaction requirement means that any visitor to an infected page can be affected, increasing the potential impact. Although availability is not directly impacted, the indirect consequences of injected scripts could include phishing or malware distribution, further amplifying risk. The medium CVSS score reflects these factors, but the real-world impact depends on the presence of the plugin and the user roles configured on the site.

European organizations should take immediate steps to mitigate this vulnerability beyond generic patching advice. First, audit all WordPress installations to identify the presence of the Magic Buttons for Elementor plugin and verify the version in use. Since no official patch links are currently available, consider temporarily disabling or uninstalling the plugin until a secure version is released. Restrict contributor-level permissions strictly, ensuring that only trusted users have content creation or editing capabilities. Implement Web Application Firewall (WAF) rules to detect and block common XSS payload patterns targeting the magic-button shortcode. Conduct thorough input validation and output encoding on any custom shortcodes or plugins developed in-house to prevent similar issues. Monitor logs for unusual activity from contributor accounts and review recent content changes for suspicious scripts. Educate content creators about the risks of injecting untrusted code and enforce strict content review workflows. Finally, keep WordPress core, themes, and all plugins updated regularly to reduce exposure to known vulnerabilities.
