This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for unauthenticated attackers to view private booking billing details — including the victim customer's first name, last name, email address, street address, city, and phone number — rendered as default values in checkout form fields by binding an arbitrary booking ID to the attacker's session. The only access control on the endpoint is a frontend nonce that is publicly emitted to all visitors via the wteL10n global on trip pages, meaning it provides CSRF protection only and does not restrict unauthenticated access.","published":"2026-08-16T07:16:30.423","modified":"2026-08-16T07:16:30.423","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.7.12/includes/classes/Abstracts/AjaxController.php#L52"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.7.12/includes/classes/Builders/FormFields/BillingFormFields.php#L87"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.7.12/includes/classes/Core/Controllers/Ajax/AddToCart.php#L232"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.7.12/includes/classes/Core/Controllers/Ajax/AddToCart.php#L31"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.7.12/includes/classes/Legacy/Cart.php#L373"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.8.3/includes/classes/Abstracts/AjaxController.php#L52"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.8.3/includes/classes/Builders/FormFields/BillingFormFields.php#L87"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.8.3/includes/classes/Core/Controllers/Ajax/AddToCart.php#L232"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.8.3/includes/classes/Core/Controllers/Ajax/AddToCart.php#L31"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.8.3/includes/classes/Legacy/Cart.php#L373"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3632552%40wp-travel-engine&new=3632552%40wp-travel-engine"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/9dc4a6f9-b663-4573-9a6d-0c96ee25308d?source=cve"}],"provenance":{"sources":["OSV.dev","NVD","FIRST.org (EPSS)"],"lastVerified":"2026-08-16T07:16:30.423"}}
