In several versions of JetBrains IntelliJ IDEA Ultimate, creating run configurations for cloud application servers leads to saving a cleartext unencrypted record of the server credentials in the IDE configuration files. If the Settings Repository plugin was then used and configured to synchronize IDE settings using a public repository, these credentials were published to this repository. The issue has been fixed in the following versions: 2019.1, 2018.3.5, 2018.2.8, and 2018.1.8.
The product stores sensitive information in cleartext within a resource that might be accessible to another control sphere.

Because the information is stored in cleartext (i.e., unencrypted), attackers could potentially read it. Even if the information is encoded in a way that is not human-readable, certain techniques could determine which encoding is being used, then decode the information. When organizations adopt cloud services, it can be easier for attackers to access the data from anywhere on the Internet. In some systems/environments such as cloud, the use of “double encryption” (at both the software and hardware layer) might be required, and the developer might be solely responsible for both layers, instead of shared responsibility with the administrator of the broader system/environment.
