NVD description

The Customer Reviews for WooCommerce plugin for WordPress is vulnerable to authentication bypass in all versions up to, and including, 5.103.0. This is due to the `create_review_permissions_check()` function comparing the user-supplied `key` parameter against the order's `ivole_secret_key` meta value using strict equality (`===`), without verifying that the stored key is non-empty. For orders where no review reminder email has been sent, the `ivole_secret_key` meta is not set, causing `get_meta()` to return an empty string. An attacker can supply `key: ""` to match this empty value and bypass the permission check. This makes it possible for unauthenticated attackers to submit, modify, and inject product reviews on any product — including products not associated with the referenced order — via the REST API endpoint `POST /ivole/v1/review`. Reviews are auto-approved by default since `ivole_enable_moderation` defaults to `"no"`.
