CVE-2026-68559Public exploitNetwork attack vector

Private board disclosure via unawaited export guard

Published Aug 19, 2026 · Updated Aug 19, 2026

Broken access control in WeKan before 9.74 allows remote authenticated users to read private board data via the Excel export route. In models/exportExcel.js, the GET /api/boards/:boardId/exportExcel handler calls the async exporterExcel.canExport(user) guard without await, so the truthy Promise bypasses board visibility checks and exporterExcel.build(res) still generates the file. Any authenticated non-member who knows a board ID can download card titles, descriptions, lists, swimlanes, members, and related metadata from otherwise private boards.
