Is this vulnerability remotely exploitable?

Yes. Any user who can reach the WeKan web interface or API and has credentials to access at least one board could potentially exploit the issue by manipulating identifiers in HTTP requests.

What level of access does an attacker need to exploit this IDOR?

The attacker typically needs a valid user account with access to at least one board or card. From there, they can attempt to reuse or guess card identifiers that belong to other boards, relying on the insufficient relationship checks on the server.

What is the safest general fix pattern for this issue?

Implement strict, server-side authorization that verifies both object ownership and relationships: for each checklist operation, ensure the cardId is loaded in the context of the provided boardId and confirm that the current user has permission to interact with that specific card. Centralizing these checks in a common authorization layer helps avoid inconsistencies.
