The ReviewX WooCommerce plugin contains a flaw that lets unauthenticated users call the allReminderSettings function in versions up to 2.2.12. This call returns authentication tokens that bypass admin restrictions, enabling the attacker to export sensitive customer information such as order records, names, email addresses, shipping addresses, phone numbers, and other user data. Thus the vulnerability exposes confidential data that should be available only to privileged users.

This vulnerability affects the ReviewX – Multi-Criteria Reviews for WooCommerce with Google Reviews & Schema plugin on any WordPress site that has it installed in versions 2.2.12 or earlier. WordPress installations that rely on this plugin for product reviews or reminders are subject to the exposure, regardless of whether other plugins or themes are present.

The CVSS score of 5.3 indicates moderate severity, but because authentication is not required, an attacker can trigger the flaw simply by sending an HTTP request to the vulnerable REST endpoint. EPSS data is not available and the issue is not listed in the CISA KEV catalog, suggesting it may not yet be widely exploited; nevertheless the potential for large‑scale data leakage makes timely mitigation necessary.
