{"cve":"CVE-2026-17087","nvd":{"published":"2026-08-16T07:16:30.423","modified":"2026-08-20T12:48:10.287","status":"Deferred","description":"The WP Travel Engine – Tour Booking Plugin – Tour Operator Software plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 6.8.4. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","score":7.5},"cwes":["CWE-862"],"references":["https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.7.12/includes/classes/Abstracts/AjaxController.php#L52","https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.7.12/includes/classes/Builders/FormFields/BillingFormFields.php#L87","https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.7.12/includes/classes/Core/Controllers/Ajax/AddToCart.php#L232","https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.7.12/includes/classes/Core/Controllers/Ajax/AddToCart.php#L31","https://plugins.trac.wordpress.org/browser/wp-travel-engine/tags/6.7.12/includes/classes/Legacy/Cart.php#L373"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:49:10.689564601+00:00"},"epss":{"cve":"CVE-2026-17087","score":0.00691,"percentile":0.52845,"date":"2026-11-01"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
