CyberRota Analysis
AI-GeneratedWekan versions prior to 10.38 are vulnerable to a denial-of-service attack due to improper handling of user authentication tokens in export API endpoints, which can lead to unhandled exceptions and process termination. This vulnerability can be exploited by attackers to disrupt service for all users by triggering a TypeError when accessing private boards with invalid tokens. Organizations using affected versions should prioritize upgrading to version 10.38 or later to mitigate this risk.

Original NVD Description
Wekan is open source kanban built with Meteor. Prior to 10.38, the /api/boards/:boardId/export, /api/boards/:boardId/attachments/:attachmentId/export, /api/boards/:boardId/export/csv, and /api/boards/:boardId/exportExcel handlers in models/export.js and models/exportExcel.js looked up a user from the attacker-controlled authToken query parameter and immediately called user._id.toString() without checking whether ReactiveCache.getUser() returned undefined. A request for a private board with an unknown token therefore threw a TypeError from an asynchronous route, producing an unhandled rejection that could terminate the Wekan process and deny service to all users. Version 10.38 adds a 401 guard after every export token lookup and wraps export handlers with safeRoute() so unexpected exceptions become controlled responses. This issue is fixed in version 10.38.
