Description
The Simply Schedule Appointments plugin for WordPress is vulnerable to Sensitive Information Exposure via the appointment types REST endpoint in all versions up to, and including, 1.6.12.35, due to the public appointment type listing returning the connected Google Calendar identifiers and the web meeting settings without redaction for unprivileged callers. This makes it possible for unauthenticated attackers to retrieve the site owner's Google Calendar IDs, which are often email addresses, and the web meeting links configured for appointment types.
