## Technical details

An Insecure Direct Object Reference (IDOR) vulnerability exists in WeKan's checklist creation and related API routes. The application fails to validate that a provided 'cardId' actually belongs to the specified 'boardId' during request processing. A remote attacker can exploit this by manipulating these identifiers in network requests to perform actions on cards across different boards. This bypasses intended authorization boundaries, allowing for unauthorized checklist modifications. The issue is addressed in version 8.19 by implementing server-side checks to verify card-to-board ownership.
