CVE-2026-25566Network attack vector

Unauthorized cross-board card moves via unchecked destinations

Published Feb 7, 2026 · Updated Feb 7, 2026

Incorrect authorization in WeKan before 8.19 allows remote authenticated users to move cards into boards they cannot access. Within the cross-board move path in models/cards.js, the server updates the card without checking destination-board access or binding the supplied list and swimlane IDs to that board. Any account able to move a card from an accessible board can alter card placement across board boundaries, including into a board that the account cannot access.
