Contributor Cross Site Scripting (XSS) in King Addons for Elementor <= 51.1.86 versions.
AnalysisAI
Authenticated stored cross-site scripting in the King Addons for Elementor WordPress plugin (versions up to and including 51.1.86) allows an attacker holding a Contributor-level account to inject a script payload through an insufficiently sanitized addon widget or field, which then executes in the trusted wp-admin origin when a higher-privileged user (editor or administrator) views or previews the affected content. Rated CVSS 6.5 (CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:C/C:L/I:L/A:L), the flaw requires both an authenticated Contributor account (PR:L) and victim interaction (UI:R), so it is not remotely exploitable by anonymous visitors and does not self-execute. …
