Description
FacturaScripts is an open source accounting and invoicing software. In versions 2025.92 and earlier, the application fails to validate the nick parameter during a POST request to the EditUser controller. Although the user interface prevents editing this field, a user can bypass this restriction by intercepting the request and modifying the nick form-data parameter to rename any account, including the administrator account. This leads to unauthorized modification of a field intended to be immutable.
