CVE-2026-68561 Detail
Received
This CVE record has recently been published to the CVE List and has been included within the NVD dataset. DescriptionWekan is open source kanban built with Meteor. Prior to 9.89, the second Boards.allow({ update }) rule in server/permissions/boards.js called canUpdateBoardSort in server/lib/utils.js, which authorized any board member whenever fieldNames included sort. Because Meteor combines allow rules with OR semantics and applies the complete modifier, a comment-only or read-only member could send one Boards.update with $set values for sort, members, permission, and title, make themselves the sole board administrator, expose a private board, and evict the legitimate owner; the last-admin deny rule inspected only $pull and did not block a wholesale $set of members. Version 9.89 requires sort to be the only modified field and rejects $set member arrays that remove the last active administrator. This issue is fixed in version 9.89. Metrics
