This is due to the admin_user_create_cus AJAX handler lacking any authentication or capability check before passing the attacker-supplied truebooker_wp_user_id parameter directly to wp_update_user. This makes it possible for unauthenticated attackers to overwrite the email address of any WordPress user — including an administrator — and then complete the standard WordPress lost-password flow to fully take over the targeted account."}],"title":"TrueBooker <= 1.2.6 - Unauthenticated Authorization Bypass Through User-Controlled Key to Account Takeover to 'truebooker_wp_user_id' Parameter","references":[{"url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/73251a74-5be3-446b-8e0a-ff2d1484c467?source=cve"},{"url":"https://plugins.svn.wordpress.org/truebooker-appointment-booking/tags/1.2.6/main/function_ajax.php"},{"url":"https://plugins.svn.wordpress.org/truebooker-appointment-booking/tags/1.2.6/main/config/truebooker-style.php"},{"url":"https://plugins.svn.wordpress.org/truebooker-appointment-booking/tags/1.2.6/templates/login-register.php"},{"url":"https://plugins.trac.wordpress.org/changeset/3640018/truebooker-appointment-booking"}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-639 Authorization Bypass Through User-Controlled Key","cweId":"CWE-639","type":"CWE"}]}],"metrics":[{"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","baseScore":9.8,"baseSeverity":"CRITICAL"}}],"credits":[{"lang":"en","type":"finder","value":"Décio Brandão"}],"timeline":[{"time":"2026-07-29T18:26:01.000Z","lang":"en","value":"Vendor Notified"},{"time":"2026-08-18T14:52:24.000Z","lang":"en","value":"Disclosed"}]},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-08-21T16:07:23.383578Z","id":"CVE-2026-18315","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-08-21T16:15:25.173Z"}}]}}
