The Responsive Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) in multiple widgets. This occurs because the plugin does not properly sanitize or escape HTML input, allowing authenticated users with Contributor or higher privileges to inject malicious scripts. These scripts are stored and executed in the context of any user who accesses the compromised page, potentially leading to session hijacking or other script-based attacks. The vulnerability affects all versions up to 1.6.4. There is no vendor advisory or patch information provided at this time.

An attacker with Contributor-level access or higher can exploit this vulnerability to inject persistent malicious scripts into pages generated by the plugin. These scripts execute in the browsers of users who visit the infected pages, potentially leading to theft of user credentials, session tokens, or other sensitive information. The vulnerability does not affect availability but impacts confidentiality and integrity. No known exploits in the wild have been reported.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict Contributor-level access to trusted users only and consider disabling or removing the affected plugin if possible. Monitor for plugin updates from cyberchimps and apply them promptly once released.
