My Calendar <= 3.7.14 - Insecure Direct Object Reference to Unauthenticated Sensitive Information Disclosure via 'vcal' Parameter

My Calendar <= 3.7.14 - Insecure Direct Object Reference to Unauthenticated Sensitive Information Disclosure via 'vcal' Parameter

The My Calendar – Accessible Event Manager plugin for WordPress is vulnerable to Insecure Direct Object Reference in all versions up to, and including, 3.7.14 via the 'vcal' parameter due to missing validation on a user controlled key. This makes it possible for unauthenticated attackers to enumerate occurrence IDs and access the full iCalendar export of non-public, draft, trashed, and personal calendar events, disclosing sensitive event metadata including titles, descriptions, dates, locations, organizer and host details, permalinks, and related calendar metadata.
Mögliche Gegenmaßnahme
My Calendar – Accessible Event Manager: Update to version 3.7.15, or a newer patched version
