The King Addons for Elementor plugin in versions up to and including 51.1.86 contains a Cross Site Scripting (XSS) vulnerability exploitable by a user with Contributor privileges. This enables injection of a malicious script into the site.

Cross Site Scripting (XSS) vulnerability in King Addons for Elementor up to version 51.1.85. A contributor can inject malicious scripts.

The King Addons for Elementor plugin in versions up to and including 51.1.81 contains an Insecure Direct Object References (IDOR) vulnerability. An unauthenticated attacker can access objects they should not have access to.

The King Addons for Elementor WordPress plugin before version 51.1.81 does not perform per-object authorization checks on a group of image-optimization actions, gating them only on a coarse capability that lower-privileged users also hold and never confirming ownership of the targeted object, allowing authenticated users with author-level access and above to disclose absolute file paths for, overwrite the bytes of, and site-wide re-reference media belonging to other users, including administrators.

The King Addons for Elementor WordPress plugin before version 51.1.81 does not perform any capability, post-status, or password check before rendering the content of a user-supplied post, allowing users with Contributor-level access and above to read the content of private, draft, pending, and password-protected posts they are not authorized to access.

The King Addons for Elementor WordPress plugin before version 51.1.81 does not perform an object-level authorization check when importing template content into a page, allowing users with contributor-level access and above to overwrite the Elementor content of arbitrary posts and pages, including those owned by administrators, and to inject JavaScript through a widget setting that is output without escaping, resulting in Stored Cross-Site Scripting that executes in the session of any user who views the affected page.

The King Addons for Elementor WordPress plugin before version 51.1.77 does not escape a widget display-style setting before outputting it in an HTML attribute, allowing users with Contributor-level access and above to store JavaScript that executes in the browser of any visitor to the affected page, including logged-in administrators.

The King Addons for Elementor plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'form_page_id' parameter in versions up to and including 51.1.62.

The King Addons for Elementor plugin for WordPress is vulnerable to multiple Contributor+ DOM-Based Stored Cross-Site Scripting vulnerabilities in all versions up to, and including, 51.1.38. This is due to insufficient input sanitization and output escaping across multiple widgets and features. The plugin uses esc_attr() and esc_url() within JavaScript inline event handlers (onclick attributes), which allows HTML entities to be decoded by the DOM, enabling attackers to break out of the JavaScript context. Additionally, several JavaScript files use unsafe DOM manipulation methods (template literals, .html(), and window.location.href with unvalidated URLs) with user-controlled data. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts via Elementor widget settings that execute when a user accesses the injected page or when an administrator previews the page in Elementor's editor. The vulnerability was partially patched in version 5.1.51.

The King Addons for Elementor plugin for WordPress up to version 51.1.39 contains a stored Cross-Site Scripting (XSS) vulnerability in the Pricing Slider, Pricing Calculator, and Image Accordion widgets. This is due to insufficient input sanitization and output escaping on user-supplied attributes.
