Contributor Cross Site Scripting (XSS) in King Addons for Elementor <= 51.1.85 versions.
AnalysisAI
Stored cross-site scripting in the King Addons for Elementor WordPress plugin (versions through 51.1.85) allows an authenticated attacker with Contributor-level privileges or higher to inject JavaScript that executes in the browser of a higher-privileged user - typically an administrator - who views or previews the crafted content. Exploitation requires an existing low-privilege account plus a separate, subsequent user-interaction step (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L), and the scope change (S:C) reflects that the script runs with the victim's privileges rather than the attacker's, enabling session or content tampering in an administrative context. …
