This is due to the `UpdateProviderCommandHandler` failing to validate changes to the `externalId` field when a Provider (Employee) user updates their own profile. The `externalId` maps directly to a WordPress user ID and is passed to `wp_set_password()` and `wp_update_user()` without authorization checks. This makes it possible for authenticated attackers, with Provider-level (Employee) access and above, to take over any WordPress account — including Administrator — by injecting an arbitrary `externalId` value when updating their own provider profile."}],"id":"CVE-2026-5465","lastModified":"2026-06-17T10:59:04.580","metrics":{"cvssMetricV31":[{"cvssData":{"attackComplexity":"LOW","attackVector":"NETWORK","availabilityImpact":"HIGH","baseScore":8.8,"baseSeverity":"HIGH","confidentialityImpact":"HIGH","integrityImpact":"HIGH","privilegesRequired":"LOW","scope":"UNCHANGED","userInteraction":"NONE","vectorString":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"exploitabilityScore":2.8,"impactScore":5.9,"source":"security@wordfence.com","type":"Secondary"}],"ssvcV203":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","ssvcData":{"id":"CVE-2026-5465","options":[{"exploitation":"none"},{"automatable":"no"},{"technicalImpact":"total"}],"role":"CISA Coordinator","timestamp":"2026-04-07T13:13:09.198377Z","version":"2.0.3"}}]},"published":"2026-04-07T07:16:24.050","references":[{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/ameliabooking/tags/2.1.3/src/Application/Commands/User/Provider/UpdateProviderCommandHandler.php#L146"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/ameliabooking/tags/2.1.3/src/Application/Commands/User/Provider/UpdateProviderCommandHandler.php#L219"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/ameliabooking/tags/2.1.3/src/Application/Commands/User/Provider/UpdateProviderCommandHandler.php#L239"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/browser/ameliabooking/tags/2.1.3/src/Application/Controller/User/Provider/UpdateProviderController.php#L30"},{"source":"security@wordfence.com","url":"https://plugins.trac.wordpress.org/changeset/3499608/ameliabooking/trunk/src/Application/Commands/User/Provider/UpdateProviderCommandHandler.php"},{"source":"security@wordfence.com","url":"https://www.wordfence.com/threat-intel/vulnerabilities/id/a4204099-1065-4167-8b42-3da25945236c?source=cve"}],"sourceIdentifier":"security@wordfence.com","vulnStatus":"Deferred","weaknesses":[{"description":[{"lang":"en","value":"CWE-639"}],"source":"security@wordfence.com","type":"Secondary"}]}
