Executive Summary

CVE-2026-2209 is an improper authorization vulnerability in Wekan versions up to 8.18, specifically in the function setCreateTranslation within the Custom Translation Handler component. This flaw is an Insecure Direct Object Reference (IDOR) that allows non-admin users to create, modify, or delete custom translations without proper permissions.

The vulnerability arises because the system lacks adequate authorization checks, enabling unauthorized remote attackers to manipulate translation data that should be restricted to administrators only.

The issue was fixed in version 8.19 by adding server-side authorization checks that ensure only admin users can perform translation operations.

Impact Analysis

This vulnerability can impact you by allowing unauthorized users to manipulate custom translations in your Wekan instance, potentially leading to unauthorized changes in displayed content.

Such unauthorized modifications can affect the integrity and availability of translation data, possibly causing confusion or misinformation for users relying on accurate translations.

Because the attack can be launched remotely with low complexity and no user interaction, it poses a moderate security risk.

Detection Guidance

There is no specific detection method or network/system commands provided in the available resources to identify this vulnerability directly.

Mitigation Strategies

The immediate and recommended mitigation step is to upgrade Wekan to version 8.19 or later, which contains the patch fixing this vulnerability.

The patch includes adding strict server-side authorization checks to ensure only admin users can create, update, or delete custom translations, preventing unauthorized access.

Specifically, the fix routes deletion requests through a dedicated server method with admin verification and protects all translation modification methods with admin checks.
