A missing permission check in Jenkins Datadog Plugin 5.4.1 and earlier allows attackers with Overall/Read permission to connect to an attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing credentials stored in Jenkins.

The Java client for the Datadog API before version 1.0.0-beta.9 has a local information disclosure of sensitive information downloaded via the API using the API Client. The Datadog API is executed on a unix-like system with multiple users. The API is used to download a file containing sensitive information. This sensitive information is exposed locally to other users. This vulnerability exists in the API Client for version 1 and 2. The method `prepareDownloadFilecreates` creates a temporary file with the permissions bits of `-rw-r--r--` on unix-like systems. On unix-like systems, the system temporary directory is shared between users. As such, the contents of the file downloaded via the `downloadFileFromResponse` method will be visible to all other users on the local system. Analysis of the finding determined that the affected code was unused, meaning that the exploitation likelihood is low. The unused code has been removed, effectively mitigating this issue. This issue has been patch…

The Datadog Plugin stores an API key to access the Datadog service in the global Jenkins configuration. While the API key is stored encrypted on disk, it was transmitted in plain text as part of the configuration form. This could result in exposure of the API key for example through browser extensions or cross-site scripting vulnerabilities. The Datadog Plugin now encrypts the API key transmitted to administrators viewing the global configuration form.
