As a result, an authenticated user with permission to create or modify customer users may create a customer user whose email address is already assigned to a customer user in another backend.</p> <p>This can result in multiple customer user records representing the same communication identity. Depending on the affected workflow and backend resolution, customer-related information or email communication may subsequently be associated with or exposed to the wrong customer user.</p> <p>The vulnerability does not allow unauthenticated users to create customer accounts. Exploitation requires permissions to create or modify customer users.</p> <p>This issue affects OTRS:</p> <p>* 7.0.X * 8.0.X * 2023.X * 2024.X * 2025.X * 2026.X before 2026.7.X</p> <p>Please note that ((OTRS)) Community Edition 6.x and before are vulnerable.
