CVE-2021-21331

{"containers": {"cna": {"affected": [{"product": "datadog-api-client-java", "vendor": "DataDog", "versions": [{"status": "affected", "version": "< 1.0.0-beta.9"}]}], "descriptions": [{"lang": "en", "value": "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.

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 patched in version 1.0.0-beta.9.
