Unauthenticated Cross Site Scripting (XSS) in Unlimited Elements For Elementor (Free Widgets, Addons, Templates) <= 2.0.17 versions.

The CVSS 7.1 rating reflects a scope change (S:C), meaning the injected payload escapes the plugin's own origin and can compromise administrator browser sessions. …

Vulnerability AssessmentAI

Exploitation Exploitation requires: (1) the target WordPress site has Unlimited Elements For Elementor installed and active in version <= 2.0.17; (2) an attacker can reach a plugin-handled input endpoint without any WordPress authentication (PR:N confirmed by CVSS vector); (3) a victim - most critically a logged-in WordPress administrator or privileged user - subsequently loads the page or Elementor element containing the injected payload (UI:R). … Additional conditions and limiting factors are described in the full assessment.
Risk Assessment The CVSS 7.1 base score is driven by network reachability (AV:N), low attack complexity (AC:L), no authentication requirement (PR:N), required user interaction (UI:R), and scope change (S:C) - a realistic profile for stored or reflected XSS in a widely deployed WordPress plugin. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in.
