CVE-2026-68561Public exploitNetwork attack vector

Board takeover via permissive sort update rule

Published Aug 19, 2026 · Updated Aug 25, 2026

Incorrect authorization in WeKan before 9.89 allows remote authenticated users to take over boards through a crafted collection update. The canUpdateBoardSort rule approves an entire Boards.update modifier whenever fieldNames merely includes sort, while the last-admin deny rule ignores wholesale $set replacements of members. Any active board member, including comment-only or read-only users, can become the sole administrator, publish a private board, rewrite its fields, and evict its owner without user interaction.
