CVE-2026-85410: Auth Bypass (CVSS 8.1)

Description

The Master Addons for Elementor – Elementor Addons, Widgets, Mega Menu Builder, Popup Builder, Widget Builder & Template Kits plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 3.2.2. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to modify the title and metadata of arbitrary WordPress posts or permanently delete arbitrary WordPress posts by supplying an attacker-controlled popup_id. The required nonce is emitted on the edit-jltma_popup admin screen, which is accessible to Contributors because the jltma_popup custom post type is registered with capability_type='post'.
