description

Elementor Website Builder installations using the elementor package through version 4.3.5 are affected by reflected cross-site scripting. An unauthenticated attacker may cause script to run in a user's browser when that user interacts with a crafted request.

mitigation

Update to a vendor release that remediates the issue when one is identified; no fixed version is recorded in the advisory data. Until then, reduce exposure with web-application filtering for suspected XSS requests and caution users against following untrusted links to affected sites.
