CVE-2025-46260 is a Stored Cross-site Scripting (XSS) vulnerability classified under CWE-79, affecting the wowDevs Sky Addons for Elementor plugin. This plugin is an extension for the popular WordPress page builder Elementor, which is widely used to create and customize websites without coding. The vulnerability arises due to improper neutralization of user-supplied input during web page generation, allowing malicious scripts to be stored and later executed in the context of users visiting the affected website. Specifically, the flaw exists in versions up to 3.0.1 of Sky Addons for Elementor. An attacker can exploit this vulnerability by injecting malicious JavaScript payloads into input fields or content areas that are not properly sanitized or escaped. When other users or administrators view the compromised content, the malicious script executes in their browsers, potentially leading to session hijacking, credential theft, defacement, or distribution of malware. The vulnerability does not require prior authentication, increasing its risk profile, and no user interaction beyond visiting the affected page is necessary for exploitation. Although no known public exploits have been reported yet, the presence of stored XSS in a widely used WordPress plugin poses a significant risk, especially given the popularity of Elementor and its addons in website development. The lack of an official patch at the time of reporting further elevates the urgency for mitigation.

For European organizations, the impact of this vulnerability can be substantial. Many European businesses, government agencies, and non-profits rely on WordPress and Elementor for their web presence due to ease of use and localization support. A successful exploit could lead to unauthorized access to user sessions, theft of sensitive information such as login credentials or personal data, and potential defacement or disruption of public-facing websites. This can damage organizational reputation, violate data protection regulations such as GDPR, and result in financial losses or legal penalties. Additionally, attackers could leverage the vulnerability to distribute malware or conduct phishing campaigns targeting European users. The stored nature of the XSS means that once injected, the malicious payload can affect multiple visitors over time, amplifying the impact. Organizations in sectors with high web traffic or handling sensitive data (e.g., finance, healthcare, government) are particularly at risk. The medium severity rating reflects the balance between the ease of exploitation and the potential damage, but the absence of a patch and the widespread use of the affected plugin increase the threat level in practice.

To mitigate this vulnerability, European organizations should take immediate and specific actions beyond generic advice: 1) Conduct an inventory of all WordPress sites using Elementor and specifically the Sky Addons plugin to identify affected instances. 2) Temporarily disable or remove the Sky Addons for Elementor plugin until an official patch or update is released by wowDevs. 3) Implement Web Application Firewall (WAF) rules tailored to detect and block common XSS payload patterns targeting the plugin's input fields. 4) Review and harden input validation and output encoding practices on affected sites, possibly by customizing or extending the plugin code to sanitize inputs if immediate patching is not feasible. 5) Monitor website logs and user reports for suspicious activity or unexpected content injections. 6) Educate site administrators and content editors about the risks of injecting untrusted content and encourage the use of security plugins that can detect XSS attempts. 7) Once a patch is available, prioritize prompt testing and deployment to restore secure functionality. 8) Regularly back up website data to enable quick recovery in case of compromise. These targeted steps will reduce exposure and help maintain compliance with European data protection standards.
