The ElementsKit Elementor Addons plugin for WordPress contains a stored XSS vulnerability (CWE-79) in its Image Accordion widget due to improper neutralization of user-supplied input. Authenticated users with contributor or higher privileges can inject arbitrary JavaScript code that executes in the context of other users viewing the compromised page. This vulnerability affects all versions up to 3.4.0. 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 observed.

Successful exploitation allows an authenticated contributor or higher to inject persistent malicious scripts into pages, which execute in the browsers of users who view those pages. This can lead to unauthorized disclosure of information and modification of content within the affected WordPress site. There is no impact on availability reported. The vulnerability does not require user interaction beyond viewing the injected page.

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict contributor-level access to trusted users only and consider disabling or avoiding use of the Image Accordion widget in the ElementsKit Elementor Addons plugin. Monitor for updates from the vendor regarding patches or official mitigations.
