CVE-2021-21430
May 10, 2021
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.
