The vulnerability explicitly identifies DataSourceProvider, FileProvider, and Mime4JWorkaround classes as using File.createTempFile(). This method creates temporary files with insecure permissions (world-readable/writable by default), which is a known anti-pattern (CWE-378). The GitHub commit diff shows direct replacements of File.createTempFile() with Files.createTempFile().toFile() in multiple test classes, confirming the insecure pattern was present. While exact file paths for the main classes aren't provided, the advisory's specificity about the affected classes and the CWE mapping provide high confidence.
