Pixar Labs vulnerabilities and threats

The Master Addons for Elementor plugin for WordPress has an authorization bypass vulnerability in all versions up to and including 3.2.2. This flaw allows authenticated users with contributor-level access or higher to modify or delete arbitrary WordPress posts by exploiting improper authorization checks related to popup management. The vulnerability arises because the plugin does not properly verify user permissions when handling actions involving popup IDs.

Missing Authorization vulnerability in Pixar Labs Master Addons for Elementor allows Privilege Abuse. This issue affects Master Addons for Elementor: from n/a through 3.2.2.

The Master Addons for Elementor – Elementor Addons, Widgets, Mega Menu Builder, Popup Builder, Widget Builder & Template Kits plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 3.1.9 via the upload_template_kit function. This is due to incorrect authorization on the upload_template_kit() AJAX handler, which requires only upload_files capability instead of the manage_options required by all sibling handlers, combined with missing per-entry file type filtering after ZIP extraction. This makes it possible for authenticated attackers, with editor-level access and above, to upload files that may be executable, which makes remote code execution possible. Editors can satisfy the nonce requirement because the required nonces are localized on the standard Pages list screen, which is accessible to any user with the edit_pages capability.
