What is CVE-2026-4664?

The Customer Reviews for WooCommerce plugin allows unauthenticated attackers to bypass permission checks, enabling them to submit, modify, and inject product reviews. This vulnerability arises from the insecure handling of the 'key' parameter in the 'create_review_permissions_check()' function, which does not properly verify whether the 'ivole_secret_key' is set. As a result, attackers can exploit this flaw via the REST API endpoint to manipulate reviews for any product, drastically undermining the integrity of user-generated content. By default, reviews submitted in this manner are auto-approved, further compounding the risks associated with this vulnerability.

Affected Version(s)
