{"id":"CVE-2026-8791","state":"PUBLISHED","title":"Booking System Trafft <= 1.0.17 - Authenticated (Subscriber+) Stored Cross-Site Scripting","description":"The Booking System Trafft plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `bookingWebsiteUrl` setting in all versions up to, and including, 1.0.17 due to a missing capability check on the `set_options` AJAX action when the plugin is operating in agency mode. The `trafftSetOptions()` handler verifies a nonce that is exposed to any authenticated user (it is printed inline on every admin page, including profile.php) but performs no capability check before calling `update_option('trafft_option', ['bookingWebsiteUrl' => ...])`. This setting is then used by `trafftAdminAssets()` to enqueue `<bookingWebsiteUrl>/embed.js` as a script on every front-end page that renders the booking shortcode. This makes it possible for authenticated attackers, with Subscriber-level access and above, to point the embed-script URL at an attacker-controlled origin and execute arbitrary JavaScript in the browser of every site visitor (including admins).","publishedAt":"2026-07-29T09:31:15.606Z","updatedAt":"2026-07-29T15:22:28.952Z","severity":{"score":6.4,"label":"Medium","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","source":"Wordfence"},"assigner":"Wordfence","products":["ameliabooking Booking System Trafft"],"affected":[{"vendor":"ameliabooking","product":"Booking System Trafft","defaultStatus":"unaffected","versions":[{"version":"<= 1.0.17","status":"affected"}]}],"references":["https://www.wordfence.com/threat-intel/vulnerabilities/id/e93060cf-2df3-4d45-a1f2-304f443d58bc?source=cve","https://plugins.trac.wordpress.org/browser/booking-system-trafft/trunk/trafft.php#L139","https://plugins.trac.wordpress.org/browser/booking-system-trafft/tags/1.0.17/trafft.php#L139","https://plugins.trac.wordpress.org/browser/booking-system-trafft/trunk/trafft.php#L155","https://plugins.trac.wordpress.org/browser/booking-system-trafft/tags/1.0.17/trafft.php#L155","https://plugins.trac.wordpress.org/browser/booking-system-trafft/trunk/trafft.php#L176","https://plugins.trac.wordpress.org/browser/booking-system-trafft/tags/1.0.17/trafft.php#L176","https://plugins.trac.wordpress.org/browser/booking-system-trafft/trunk/trafft.php#L325","https://plugins.trac.wordpress.org/browser/booking-system-trafft/tags/1.0.17/trafft.php#L325","https://plugins.trac.wordpress.org/browser/booking-system-trafft/trunk/trafft.php#L354","https://plugins.trac.wordpress.org/browser/booking-system-trafft/tags/1.0.17/trafft.php#L354"],"weaknesses":["CWE-79"],"ingestedAt":"2026-10-29T20:13:26.108Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/8xxx/CVE-2026-8791.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-8791","state":"PUBLISHED","datePublished":"2026-07-29T09:31:15.606Z","dateUpdated":"2026-07-29T15:22:28.952Z","assignerShortName":"Wordfence","assignerOrgId":"b15e7b5b-3da4-40ae-a43c-f7aa60e62599","dateReserved":"2026-05-17T20:50:37.972Z"},"containers":{"cna":{"title":"Booking System Trafft <= 1.0.17 - Authenticated (Subscriber+) Stored Cross-Site Scripting","descriptions":[{"lang":"en","value":"The Booking System Trafft plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the `bookingWebsiteUrl` setting in all versions up to, and including, 1.0.17 due to a missing capability check on the `set_options` AJAX action when the plugin is operating in agency mode.
