Vulnerability Title
Wekan: Read-only board members can create/modify/delete Custom Fields (privilege escalation via read-level authz on write ops)
Source: NVD (National Vulnerability Database)
Vulnerability Description
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.
