      <title>CVE-2026-4664 — Customer Reviews for WooCommerce &lt;= 5.103.0 - Unauthenticated Authentication Bypass to Arbitrary Review Submission via…</title>
      <link>https://cve.radiocsirt.org/vuln/cve-2026-4664</link>
      <description>&lt;p&gt;&lt;strong&gt;Affected:&lt;/strong&gt; ivole Customer Reviews for WooCommerce&lt;/p&gt;
&lt;p&gt;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&amp;#39;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: &amp;#34;&amp;#34;` 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 `&amp;#34;no&amp;#34;`.&lt;/p&gt;</description>
