CVE-2026-18945
HighCVSS 8.2Exploitation Probability (EPSS)
Low risk4th percentile - higher than 4% of all known CVEs
Summary
The WP Helper Premium WordPress plugin before version 4.7.6 does not verify the order key when rendering its custom order confirmation page or when handling the related AJAX actions, allowing unauthenticated users to view other customers' order details, including personal information, as well as change the state of arbitrary orders. Exploitation requires WooCommerce to be active and the WP Helper Premium WordPress plugin before 4.7.6's optional order confirmation page module to be enabled.
Risk Assessment
An unauthenticated attacker can access customers' personal data and manipulate orders, potentially leading to privacy breaches, fraud, and disruption of order fulfillment.
Recommendation
Update the WP Helper Premium plugin to version 4.7.6 or later, which includes the fix. If the order confirmation page module is not needed, disable it.
