 "title": "Eventin – Events Calendar, Tickets, Registration, Booking & WooCommerce <= 4.1.26 - Authenticated (Contributor+) Insecure Direct Object Reference to Sensitive Information Exposure via Speaker REST API",
 "description": "The Eventin – Events Calendar, Tickets, Registration, Booking & WooCommerce plugin for WordPress is vulnerable to Insecure Direct Object Reference via the /eventin/v2/speakers/{id} REST endpoints in all versions up to, and including, 4.1.26, due to the permission check authorising the ID in the URL path while the handler acts on $request['id'], which a query-string or body 'id' parameter overrides. This makes it possible for authenticated attackers, with Contributor-level access and above, to read the email address and phone number of arbitrary users, including administrators.",
