The Customer Reviews for WooCommerce WordPress plugin before 5.118.0 does not sanitise and escape the content of customer reviews received via one of its endpoints, which could allow unauthenticated users to perform Stored Cross-Site Scripting attacks.

The Customer Reviews for WooCommerce WordPress plugin before 5.113.0 does not perform authentication, capability, or nonce checks on one of its media upload AJAX actions when the review media attachment feature is enabled, allowing unauthenticated users to upload media files (bounded to an image and video allowlist) to the Media Library and create attachment posts, leading to media library pollution and disk space exhaustion.

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Automattic WooCommerce woocommerce allows Stored XSS.This issue affects WooCommerce: from n/a through <= 9.7.0.

The Customer Reviews for WooCommerce plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'displayName' parameter in all versions up to, and including, 5.93.1 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with customer-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. While it is possible to invoke the AJAX action without authentication, the attacker would need to know a valid form ID, which requires them to place an order. This vulnerability can be exploited by unauthenticated attackers if guest checkout is enabled. However, the form ID still needs to be obtained through placing an order.

The WooCommerce WordPress plugin from versions 5.4.0 to 10.5.2 does not properly handle batch requests, which could allow unauthenticated users to make a logged in admin call non store/WC REST endpoints, and create arbitrary admin users via a CSRF attack for example.
