Vulnerability Overview

The Elementor plugin for WordPress is vulnerable to the creation of emergent resources due to insufficient input validation in the template "save_item" function in versions up to, and including, 3.13.3. This allows authenticated attackers, with contributor-level permissions or above, to create templates with an arbitrary post type, potentially allowing the exploitation of other plugins that depend on custom post types.

Technical Analysis

The vector marks this flaw as remotely reachable over the network, with low attack complexity — no special timing or configuration is needed, and no interaction from a victim user.

CWE-1229: Creation of Emergent Resource

The product manages resources or behaves in a way that indirectly creates a new, distinct resource that can be used by attackers in violation of the intended policy.

Remediation

How does WordSec protect against this?

The fix is the thing that ends this: Elementor Website Builder 3.13.3 closes this, and updating the plugin is the step that ends it.
