+== Sensitive Code Example
+
+Examples of sensitive file creation:
+
+[source,go]
+----
+file, _ = os.Create("/tmp/tempfile.txt") // Sensitive
+
+file, _ = os.Create(os.TempDir()+"/tempfile.txt") // Sensitive
+
+file, _ := os.OpenFile("/tmp/tempfile.txt", os.O_CREATE, 0755) // Sensitive
+
+os.WriteFile("/tmp/tempfile.txt", []byte{"sensitive"}, 0755)  // Sensitive
+----
+
+Example of sensitive directory creation:
+
+[source,go]
+----
+tempdir := "/tmp/tempdir/"
+os.Mkdir(tempdir, 0755)  // Sensitive
+file, _ := os.Create("/tmp/tempdir/tempfile.txt")
+----
+
+== Compliant Solution
+
+Compliant temporary file creation:
+
+[source,go]
+----
+file, _ := os.CreateTemp("", "example-pattern")
+----
+
+Compliant temporary directory creation:
+
+[source,go]
+----
+dir, _ := os.MkdirTemp("", "example-directory")
+filename := filepath.Join(dir, "tempfile.txt")
+file, _ := os.Create(filename)
