Checkout Custom Fields Builder for WooCommerce <= 1.1.5 - Missing Authorization to Authenticated (Subscriber+) Arbitrary Plugin Installation via 'plugin' Parameter

The Checkout Custom Fields Builder for WooCommerce plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 1.1.5. 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 subscriber-level access and above, to install and activate an arbitrary attacker-hosted plugin, resulting in remote code execution on the server. The required nonce is emitted inline on all admin pages accessible to subscribers when WooCommerce is inactive, meaning any subscriber-level user can harvest it and trigger the exploit without any additional privileges.

YITH WooCommerce Waitlist Premium <= 3.35.0 - Authenticated (Subscriber+) Privilege Escalation to Admin via wp_ajax_yith_wcwtl_add_user

The YITH WooCommerce Waitlist Premium plugin for WordPress is vulnerable to Privilege Escalation in versions up to, and including, 3.35.0. This is due to the add_user_in_waiting_list() function registered on the wp_ajax_yith_wcwtl_add_user action being missing both a capability check and a nonce verification, and using parse_str() + extract() to import attacker-controlled variables from $_POST['params'] that are then passed to wp_create_user() and $user->set_role(). This makes it possible for authenticated attackers, with Subscriber-level access and above, to elevate their privileges to that of an administrator by creating a new user account and assigning it the administrator role.

Drag and Drop File Upload for Elementor Forms <= 1.6.0 - Unauthenticated Arbitrary File Upload via 'type' Parameter

The Drag and Drop File Upload for Elementor Forms plugin for WordPress is vulnerable to Arbitrary File Upload in all versions up to, and including, 1.6.0 via the elementor_file_upload function. This is due to insufficient file type validation in the is_file_type_valid() function, which uses the attacker-controlled 'type' parameter as regex keys in the MIME allowlist, allowing blacklist bypass via a crafted extension that sanitize_file_name() later normalizes to a PHP extension. This makes it possible for unauthenticated attackers to upload files that may be executable, which makes remote code execution possible.

Sidebar Manager Light <= 1.18 - Unauthenticated Stored Cross-Site Scripting via 'sbm_description' Parameter

The Sidebar Manager Light plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'sbm_description' parameter in all versions up to, and including, 1.18 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
