Auth bypass in Wekan
CVE-2026-52892
Wekan is open source kanban built with Meteor. Prior to 9.32, Wekan REST handlers in server/models/customFields.js use read-level Authentication.checkBoardAccess instead of write-level Authentication.checkBoardWriteAccess for mutating custom-field routes. A read-only board member can call POST, PUT, and DELETE handlers for /api/boards/:boardId/custom-fields and custom-field dropdown items to create, update, or delete board custom fields. This issue is fixed in version 9.32.
