Unlimited Elements For Elementor WordPress plugin vulnerabilities

The Unlimited Elements for Elementor WordPress plugin before 2.0.21 does not sanitise and escape a parameter before using it in a SQL statement. This allows users with a role as low as subscriber to perform blind SQL injection attacks and read arbitrary data from the database. Version 2.0.18 removed the subscriber-level access, so from 2.0.18 onward the issue requires a Contributor role or above.

The Unlimited Elements for Elementor WordPress plugin before 2.0.21 does not check that a request to render widget output comes from a user allowed to make it. This allows users with a role as low as subscriber to have arbitrary WordPress shortcodes executed on the site; from version 2.0.18 onward the issue requires a Contributor role or above.

The Unlimited Elements For Elementor WordPress plugin before 2.0.20 does not perform a capability check on an AJAX action and deserializes attacker-controlled stored data through it, which makes it possible for authenticated attackers with subscriber-level access to inject arbitrary PHP objects. A partial fix in the 2.0.18 to 2.0.19 releases raised the privilege required to reach the vulnerable action to editor-level, and the issue was fully resolved in 2.0.20.
