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)."}],"title":"Booking System Trafft <= 1.0.17 - Authenticated (Subscriber+) Stored Cross-Site Scripting","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/e93060cf-2df3-4d45-a1f2-304f443d58bc?source=cve"},{"url":"https://plugins.trac.wordpress.org/browser/booking-system-trafft/trunk/trafft.php#L139"},{"url":"https://plugins.trac.wordpress.org/browser/booking-system-trafft/tags/1.0.17/trafft.php#L139"},{"url":"https://plugins.trac.wordpress.org/browser/booking-system-trafft/trunk/trafft.php#L155"},{"url":"https://plugins.trac.wordpress.org/browser/booking-system-trafft/tags/1.0.17/trafft.php#L155"},{"url":"https://plugins.trac.wordpress.org/browser/booking-system-trafft/trunk/trafft.php#L176"},{"url":"https://plugins.trac.wordpress.org/browser/booking-system-trafft/tags/1.0.17/trafft.php#L176"},{"url":"https://plugins.trac.wordpress.org/browser/booking-system-trafft/trunk/trafft.php#L325"},{"url":"https://plugins.trac.wordpress.org/browser/booking-system-trafft/tags/1.0.17/trafft.php#L325"},{"url":"https://plugins.trac.wordpress.org/browser/booking-system-trafft/trunk/trafft.php#L354"},{"url":"https://plugins.trac.wordpress.org/browser/booking-system-trafft/tags/1.0.17/trafft.php#L354"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-79 Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')","cweId":"CWE-79","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:L/I:L/A:N","baseScore":6.4,"baseSeverity":"MEDIUM"}}],"credits":[{"lang":"en","type":"finder","value":"Hardik Patel"}],"timeline":[{"time":"2026-05-17T21:05:49.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-07-28T21:30:10.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-07-29T15:21:57.742541Z","id":"CVE-2026-8791","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-07-29T15:22:28.952Z"}}]}}
