CVE-2026-68901Public exploitNetwork attack vector

Server crash via invalid authToken dereference

Published Aug 19, 2026 · Updated Aug 19, 2026

Denial of service in board export endpoints in WeKan before 10.38 allows remote authenticated users to crash the server via an invalid authToken. In models/export.js and models/exportExcel.js, the /api/boards export handlers read the attacker-controlled authToken, call ReactiveCache.getUser(), and immediately dereference user._id.toString() without checking whether the lookup returned undefined. Reachability requires the REST API to be enabled and a private board ID; the resulting uncaught TypeError escapes the async route handlers and can terminate the Wekan process for all users.
