Low risk16th percentile - higher than 16% of all known CVEs
Summary
The Prime Elementor Addons plugin for WordPress (versions up to and including 1.3.3) is vulnerable to Stored Cross-Site Scripting via Widget HTML Tag Settings due to insufficient input sanitization and output escaping. Authenticated attackers with contributor-level access or above can inject arbitrary scripts that execute whenever a user accesses an injected page. The exploit works even without the unfiltered_html capability because the payload (e.g., 'img src=x onerror=alert(document.domain)') contains no angle brackets and passes through Elementor's wp_kses_post() filter unchanged.
Risk Assessment
The risk is the injection of malicious scripts that can steal session data, redirect users, or perform other unauthorized actions in the victim's browser context.
Recommendation
Update the Prime Elementor Addons plugin to version 1.3.4 or later if available, or apply temporary mitigations such as restricting access to widget editing.

- CVE-2026-124494Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability because the html.clean() sanitizer's _normalizeURL() function decodes named entities like : to an empty string. Attackers can inject href values such as javascript: that pass the _isSafeURL() check but are decoded by browsers, executing JavaScript when victims click stored links.
- CVE-2026-124493Critical
SunEditor before 3.4.0 contains a stored cross-site scripting vulnerability in the DocumentType constructor that injects header textContent into innerHTML without HTML escaping. Attackers can store entity-encoded HTML in h1-h6 headers that executes JavaScript when editors using document:header mode initialize, enabling session cookie theft.
Original NVD description (English source)
The Prime Elementor Addons – Lightweight Elementor Widgets for Faster Pages plugin for WordPress is vulnerable to Stored Cross-Site Scripting via Widget HTML Tag Settings in all versions up to, and including, 1.3.3 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. The exploit succeeds even for users without the unfiltered_html capability because the payload (e.g., 'img src=x onerror=alert(document.domain)') contains no HTML angle brackets and therefore passes through Elementor's wp_kses_post() filter unchanged at save time.
