The Essential Addons for Elementor plugin for WordPress suffers from a stored cross-site scripting vulnerability (CWE-79) in its Filterable Gallery widget due to improper neutralization of user-supplied input. Authenticated users with contributor-level privileges or above can inject arbitrary web scripts that execute in the context of other users viewing the injected pages. This vulnerability affects all versions up to 6.0.3. The CVSS 3.1 base score is 6.4, reflecting network attack vector, low attack complexity, required privileges at the contributor level, no user interaction, and impacts on confidentiality and integrity but not availability. No patch or vendor advisory is currently provided, and no known exploits have been reported.

Successful exploitation allows an authenticated contributor or higher to inject malicious scripts that execute in other users' browsers when they access the compromised page. This can lead to information disclosure or integrity issues within the affected WordPress site. There is no impact on availability. The vulnerability requires authenticated access at contributor level or above, limiting the attack surface to users with such privileges.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict contributor-level access to trusted users only and consider disabling or limiting use of the Filterable Gallery widget. Monitor official channels from wpdevteam for updates or patches addressing this vulnerability.
