CVE-2026-4362 — ElementsKit Elementor Addons security vulnerability

Medium CVSS 6.5

The ElementsKit Elementor Addons plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the `Live_Action::reset()` function in all versions up to, and including, 3.8.2 The function is hooked to the WordPress `init` action and triggers when both `post` and `action=elementor` GET parameters are present, with no authentication or nonce verification. This makes it possible for unauthenticated attackers to overwrite the Elementor content (`_elementor_data`) of any `elementskit_widget` custom post type by visiting a specially crafted URL. The widget's custom designs, text, and configurations are permanently replaced with a blank template.

Matched remediation archetype

Authorization bypass, IDOR, and cross-tenant access

This catalog composition supplies bounded fallback guidance. Explicitly reviewed curated workflows load with the complete record below.

Check exposure

  • Map object and action authorization checks across API, UI, batch, import/export, and background-job paths.
  • Identify tenant, ownership, role, and policy boundaries for affected resources and administrative operations.
  • Use synthetic fixtures to compare intended access matrices without accessing another user's real data.

Remediate safely

  • Enforce server-side authorization at each resource access and state transition using the authenticated principal and trusted tenant context.
  • Scope data queries by tenant and ownership; treat client-supplied identifiers, roles, and policy claims as untrusted.
  • Add deny-by-default policy tests for horizontal and vertical access across every affected transport.
