What is CVE-2026-12501?

The WP Travel Engine plugin in WordPress fails to verify incoming PayPal payment notifications against the site's configured merchant account and the order total. This lax verification process allows unauthorized attackers to mark bookings as fully paid by using tokens from a compromised payment account. It's crucial for users of this plugin to upgrade to version 6.8.2 or later to mitigate the risks associated with this vulnerability.

Affected Version(s)

WP Travel Engine 0 < 6.8.2
