CVE-2026-107616: Booking for Appointments and Events Calendar <= 9.9.1 - Missing Authorization to Unauthenticated Arbitrary Event Attendee Data Exposure via '/report/event/atten

Noroxi assessment

Priority: Monitor (action score 30/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.50% (FIRST EPSS).
  • Anyone who can reach it over the internet can trigger it. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • According to CISA the attack is automatable: targets can be found by mass scanning.
  • According to the record, no fixed version is available yet.

Low priority for now. Update when a fix is released; follow the vendor's advisory.

Primary sources: NVD · CVE.org · FIRST EPSS

The Amelia plugin for WordPress is vulnerable to unauthorized access of attendee data due to a missing authorization check on the GetEventAttendeesCommandHandler::handle() function in versions up to, and including, 9.9.1. The handler only enforces the broad `amelia_read_events` capability — which the plugin's own `wpamelia-customer` role possesses — and does not verify that the authenticated user is an organizer/provider of the event referenced by the client-supplied `id` query parameter. This makes it possible for authenticated attackers, with wpamelia-customer-level access and above, to export the full CSV of attendee personally identifiable information (first/last name, email, phone, date of birth, gender, private notes, payment amounts/methods, WooCommerce order IDs, custom-field values, and uploaded-file URLs) for any Amelia event on the site by directly invoking the `/report/event/attendees` endpoint with an arbitrary event ID.
