The Booking for Appointments and Events Calendar - Amelia (Premium) plugin for WordPress is vulnerable to Privilege Escalation in versions 8.0 - 9.6.2. This is due to insufficient validation of the attacker-controlled 'type' parameter in the customer update endpoint, which allows customers to set their role to 'manager' and trigger creation of a WordPress user with the wpamelia-manager role when the 'externalId' parameter is set to 0. This makes it possible for unauthenticated attackers to escalate their privileges to administrator by first elevating to the manager role, then creating a provider entity linked to an administrator user ID and overwriting that administrator's password.

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires that a vulnerable Amelia Premium version (8.0-9.6.2) is installed and active on the target WordPress site and that the customer update endpoint is reachable - the exploit specifically depends on supplying the 'type' parameter set to 'manager' together with 'externalId' set to 0 to trigger wpamelia-manager user creation, then binding a provider entity to an administrator's user ID to overwrite that admin's password. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | All CVSS signals point to genuine high priority rather than an inflated score: the vector CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H describes remote, low-complexity, unauthenticated exploitation with no user interaction and full confidentiality/integrity/availability impact - consistent with an unauthenticated-to-administrator takeover chain. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade the Amelia Premium plugin to the first release above 9.6.2 (the vendor changelog at https://wpamelia.com/documentation/changelog/ lists the patched version - apply the latest available release; a specific fixed version is not independently confirmed in the provided data, so treat the changelog as authoritative). … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, inventory all WordPress installations running Amelia Premium versions 8.0 through 9.6.2 and review access logs and administrator accounts for unauthorized access (unexpected admin users, password changes, or new provider entities created in the past 30 days). …
