Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (0.32%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

WeKan versions prior to 8.19 contain an insecure direct object reference (IDOR) in checklist creation and related checklist routes. The implementation does not verify that the supplied cardId belongs to the supplied boardId, allowing cross-board ID tampering by manipulating identifiers.
