CVE-2025-8215 is a stored cross-site scripting vulnerability classified under CWE-79, found in the Responsive Addons for Elementor plugin for WordPress, which is widely used to extend Elementor page builder functionality. The vulnerability exists due to improper neutralization of input during web page generation, specifically insufficient sanitization and escaping of user-supplied attributes in multiple widgets. This flaw allows authenticated users with contributor-level permissions or higher to inject arbitrary JavaScript code into pages. When other users visit these pages, the injected scripts execute in their browsers, potentially leading to session hijacking, privilege escalation, or unauthorized actions within the context of the affected site. The vulnerability affects all versions up to and including 1.7.4 of the plugin. The CVSS 3.1 base score of 6.4 reflects a network attack vector with low attack complexity, requiring privileges but no user interaction, and impacts confidentiality and integrity with a scope change. Although no exploits have been observed in the wild, the vulnerability poses a significant risk due to the widespread use of WordPress and Elementor, and the common practice of granting contributor-level access to multiple users. The lack of official patches at the time of reporting necessitates immediate mitigation efforts by site administrators.

The primary impact of CVE-2025-8215 is the compromise of confidentiality and integrity of user data on affected WordPress sites. Attackers can execute arbitrary scripts, potentially stealing session cookies, redirecting users to malicious sites, or performing unauthorized actions on behalf of other users. This can lead to account takeover, data leakage, defacement, or further exploitation of the site environment. While availability is not directly affected, the reputational damage and loss of user trust can be significant. Organizations relying on this plugin for their web presence risk exposure to targeted attacks, especially if contributor-level access is granted to multiple users or third parties. The vulnerability's exploitation could also serve as a foothold for more advanced attacks within the network. Given the plugin's popularity, the scope of affected systems is broad, increasing the potential scale of impact globally.

To mitigate CVE-2025-8215, organizations should immediately audit user roles and restrict contributor-level or higher access to trusted personnel only. Implement strict input validation and output encoding on all user-supplied content within the plugin's widgets, if custom modifications are possible. Monitor and sanitize content created by contributors before publishing. Until an official patch is released, consider disabling or removing the Responsive Addons for Elementor plugin to eliminate the attack surface. Employ Web Application Firewalls (WAFs) with custom rules to detect and block suspicious script injections targeting the plugin's widgets. Regularly update WordPress core, Elementor, and all plugins to their latest versions once patches become available. Additionally, educate content contributors about the risks of injecting untrusted content and enforce multi-factor authentication to reduce the risk of compromised accounts. Conduct periodic security assessments focusing on XSS vulnerabilities in user-generated content areas.
