CVE-2021-21430
Description

Using File.createTempFile in JDK will result in creating and using insecure temporary files that can leave application and system data vulnerable to attacks. Auto-generated code (Java, Scala) that deals with uploading or downloading binary data through API endpoints will create insecure temporary files during the process. Affected generators: java (jersey2, okhttp-gson (default library)), scala-finch. The issue has been patched with Files.createTempFile and released in the v5.1.0 stable version.
