{"cve":"CVE-2026-5465","nvd":{"published":"2026-04-07T07:16:24.050","modified":"2026-06-17T10:59:04.580","status":"Deferred","description":"The Booking for Appointments and Events Calendar – Amelia plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 2.1.3. 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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-639"],"references":["https://plugins.trac.wordpress.org/browser/ameliabooking/tags/2.1.3/src/Application/Commands/User/Provider/UpdateProviderCommandHandler.php#L146","https://plugins.trac.wordpress.org/browser/ameliabooking/tags/2.1.3/src/Application/Commands/User/Provider/UpdateProviderCommandHandler.php#L219","https://plugins.trac.wordpress.org/browser/ameliabooking/tags/2.1.3/src/Application/Commands/User/Provider/UpdateProviderCommandHandler.php#L239","https://plugins.trac.wordpress.org/browser/ameliabooking/tags/2.1.3/src/Application/Controller/User/Provider/UpdateProviderController.php#L30","https://plugins.trac.wordpress.org/changeset/3499608/ameliabooking/trunk/src/Application/Commands/User/Provider/UpdateProviderCommandHandler.php"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:28:59.047572785+00:00"},"epss":{"cve":"CVE-2026-5465","score":0.00632,"percentile":0.50292,"date":"2026-10-31"},"kev":null,"osv":[],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
