{"id":"CVE-2026-17166","summary":"Event Booking Manager for WooCommerce \u003c= 5.3.7 - Missing Authorization to Authenticated (Contributor+) Site-Wide Payment Settings Modification via mep_save_payment_settings_modal AJAX Action","details":"The Event Booking Manager for WooCommerce – Sell Tickets, Event Registration, RSVP & Event Calendar plugin for WordPress is vulnerable to authorization bypass in all versions up to, and including, 5.3.7. This is due to the plugin not properly verifying that a user is authorized to perform an action. This makes it possible for authenticated attackers, with contributor-level access and above, to modify site-wide payment settings — including WooCommerce payment enablement, cart redirect behavior, login requirements for checkout, confirmation page ID, and confirmed ticket statuses — that govern how all event bookings are processed.","modified":"2026-10-06T02:35:53.371550550Z","published":"2026-07-29T01:29:41.941Z","database_specific":{"cna_assigner":"Wordfence","cwe_ids":["CWE-862"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/17xxx/CVE-2026-17166.json","unresolved_ranges":[{"extracted_events":[{"last_affected":"5.3.7"}],"source":"AFFECTED_FIELD"}]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/17xxx/CVE-2026-17166.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-17166"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/mage-eventpress/tags/5.3.7/admin/settings/global/admin_setting_panel.php#L1080"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/mage-eventpress/tags/5.3.7/admin/settings/global/admin_setting_panel.php#L1120"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/mage-eventpress/tags/5.3.7/admin/settings/global/admin_setting_panel.php#L25"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/mage-eventpress/trunk/admin/settings/global/admin_setting_panel.php#L1080"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/mage-eventpress/trunk/admin/settings/global/admin_setting_panel.php#L1120"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/browser/mage-eventpress/trunk/admin/settings/global/admin_setting_panel.php#L25"},{"type":"WEB","url":"https://plugins.trac.wordpress.org/changeset?reponame=&old=3625494%40mage-eventpress&new=3625494%40mage-eventpress"},{"type":"WEB","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/5f43e35e-55cd-45f1-b8a5-e47398d97cc2?source=cve"}],"affected":[{"package":{"name":"mage-eventpress","ecosystem":"WordPress:Plugin"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"last_affected":"5.3.7"}]}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-17166.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:L/A:N"}]}
