The Essential Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) in its Twitter Feed component. This flaw allows authenticated attackers with Contributor-level privileges or above to inject arbitrary JavaScript into pages, which executes in the context of users viewing those pages. The root cause is inadequate sanitization and escaping of user input before rendering it on web pages. This vulnerability affects all versions up to 5.9.21 and has a CVSS 3.1 base score of 6.4, reflecting a medium severity. No patch or official remediation guidance is currently documented.

An attacker with Contributor-level or higher access can exploit this vulnerability to inject malicious scripts that execute in the browsers of users who visit the compromised pages. This can lead to theft of user credentials, session hijacking, or other actions performed with the victim's privileges within the affected site. There is no indication of impact on system availability or integrity beyond the scope of script execution in user browsers. No known exploits have been reported in the wild.

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 limiting use of the Twitter Feed component in the plugin. Monitor for updates from the plugin vendor and apply patches promptly once released.
