CVE-2026-11896

Estado: AplazadaMedia (5.3)—

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.
