Technical details

The My Calendar plugin for WordPress is vulnerable to an Insecure Direct Object Reference (IDOR) via the 'vcal' parameter. This occurs due to insufficient validation of user-supplied keys when requesting iCalendar exports. An unauthenticated remote attacker can exploit this by enumerating occurrence IDs to retrieve iCalendar data for non-public events, including those in draft, trashed, or personal status. Successful exploitation results in the disclosure of sensitive metadata such as event titles, descriptions, dates, locations, and host details. The vulnerability is present in all versions up to and including 3.7.14.
