CVE-2026-8677Network attack vector

Contributor-level stored XSS via unsanitized widget tags

Published Jun 9, 2026 · Updated Jun 9, 2026

Stored XSS in WP Messiah Prime Elementor Addons 1.3.3 and earlier allows remote authenticated users to inject scripts through widget tag settings. The plugin passes angle-bracket-free event-handler payloads through Elementor's wp_kses_post() filter at save time and later renders the stored tag setting without sufficient output escaping. Contributor-level access is required, and the injected JavaScript executes whenever a user opens the affected page, exposing that user's browser session to script-controlled actions.
