CVE-2021-21430

Description

OpenAPI Generator allows generation of API client libraries (SDK generation), server stubs, documentation and configuration automatically given an OpenAPI Spec. 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.
