Who should care

Defenders responsible for Wekan deployments should assess exposure and apply the fix to prevent unauthorized access to sensitive board data. This includes verifying the current Wekan version, restricting access to the affected route, and monitoring for unauthorized access. Security teams should review the vulnerability details and ensure that appropriate measures are taken to protect against potential data exposure.

Why it matters

CVE-2026-68559 is a medium-severity vulnerability in Wekan that allows authenticated non-members to access private board data. Defenders should prioritize verifying exposure and applying the fix to prevent potential data exposure.

• Potential unauthorized access to private board data.
• Need to verify Wekan version and apply the fix.
• Possible data exposure for unauthenticated users.

Technical summary

The /api/boards/:boardId/exportExcel route in Wekan versions 9.57-9.73 called the asynchronous exporterExcel.canExport(user) authorization guard without awaiting it, allowing any authenticated non-member to download private board data. This issue is due to a flawed authorization guard. The fix is in version 9.74, which awaits the authorization guard properly, preventing unauthorized access to sensitive board data. Defenders should prioritize verifying exposure and applying the fix to prevent potential data exposure.
