CVE-2026-12501: CWE-345 Insufficient Verification of Data Authenticity in WP Travel Engine
WP Travel Engine WordPress plugin versions before 6.8.2 contain a vulnerability where PayPal payment notifications are not properly verified. This allows attackers to mark bookings as paid by sending payment notifications to an attacker-controlled account without authenticating the payment or verifying the amount.
AI Analysis
Technical Summary
CVE-2026-12501 describes an insufficient verification of data authenticity (CWE-345) in the WP Travel Engine WordPress plugin prior to version 6.8.2. The plugin fails to verify that incoming PayPal payment notifications correspond to the site's configured merchant account and that the payment amount matches the order total. This flaw allows unauthenticated attackers to mark bookings as fully paid by submitting payment notifications linked to an attacker-controlled PayPal account.
Potential Impact
An attacker can manipulate the booking payment status without making a legitimate payment to the merchant. This leads to unauthorized marking of bookings as paid, potentially causing financial loss or fraud for the site operator. There is no confidentiality or availability impact reported.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or patch link is provided in the available data. Until a patch is available, site operators should monitor vendor communications for updates and consider additional manual verification of payment notifications.
