CVE-2026-1897Network attack vector

Authenticated board-history disclosure via missing visibility checks

Published Feb 5, 2026 · Updated Feb 5, 2026

Missing authorization in WeKan 8.0 through 8.20 allows remote authenticated users to read position-history data from inaccessible boards. The Position History Meteor methods accept board, swimlane, list, or card identifiers and return tracking data without verifying that the caller can view the owning board. Any signed-in account can query original positions, movement state, descriptions, or board history for identifiers it knows, while the published impact is limited to confidentiality.
