CVE-2025-6686 is a stored Cross-Site Scripting (XSS) vulnerability identified in the Magic Buttons for Elementor WordPress plugin developed by rexdot. This vulnerability affects all versions up to and including version 1.0 of the plugin. The root cause is improper input sanitization and insufficient output escaping on user-supplied attributes within the plugin's magic-button shortcode. Specifically, authenticated users with contributor-level privileges or higher can inject arbitrary JavaScript code into pages via the shortcode parameters. Because the malicious script is stored persistently in the website's content, it executes every time any user accesses the compromised page. The vulnerability is classified under CWE-79, which relates to improper neutralization of input during web page generation. 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 equivalent to contributor or above, does not require user interaction, and impacts confidentiality and integrity with a scope change. No known exploits are currently reported in the wild, and no official patches have been linked yet. The vulnerability allows attackers to execute arbitrary scripts in the context of the vulnerable website, potentially leading to session hijacking, defacement, or unauthorized actions performed on behalf of other users. Since the exploit requires authenticated access at contributor level or higher, it is not trivially exploitable by anonymous users but remains a significant risk in environments with multiple user roles and contributors.

For European organizations using WordPress sites with the Magic Buttons for Elementor plugin, this vulnerability poses a tangible risk to website integrity and user trust. Attackers with contributor-level access could inject malicious scripts that execute in the browsers of site visitors or administrators, potentially leading to credential theft, unauthorized actions, or the spread of malware. This can result in data breaches, reputational damage, and regulatory non-compliance, especially under GDPR where personal data exposure is involved. The scope change indicated by the CVSS vector means that the vulnerability can affect resources beyond the initially compromised component, potentially impacting other parts of the website or connected systems. Given the widespread use of WordPress in Europe for corporate, governmental, and e-commerce websites, exploitation could disrupt business operations and customer interactions. While the requirement for authenticated access limits the attack surface, insider threats or compromised contributor accounts increase the risk. The lack of current known exploits provides a window for mitigation but also means organizations should proactively address the issue to prevent future attacks.

European organizations should immediately audit their WordPress installations to identify the presence of the Magic Buttons for Elementor plugin. Since no official patch is currently linked, organizations should consider the following specific mitigations: 1) Restrict contributor-level access strictly to trusted users and review user roles and permissions to minimize unnecessary privileges. 2) Implement Web Application Firewall (WAF) rules that detect and block suspicious shortcode attribute inputs or script injection patterns targeting the magic-button shortcode. 3) Employ Content Security Policy (CSP) headers to limit the execution of unauthorized scripts on affected sites. 4) Monitor website content and logs for unusual shortcode usage or unexpected script insertions. 5) Temporarily disable or remove the Magic Buttons for Elementor plugin if feasible until a patch is released. 6) Educate content contributors about the risks of injecting untrusted code and enforce strict input validation on any user-generated content. 7) Keep WordPress core and all plugins updated and subscribe to vulnerability advisories for timely patching once available. These targeted actions go beyond generic advice by focusing on access control, detection, and containment specific to this vulnerability's exploitation vector.
