+      `yaml.unsafe_load`, `yaml.Loader`, `yaml.CLoader`, and `yaml.UnsafeLoader`
+      are all known to be unsafe methods of deserializing YAML. An attacker with
+      control over the YAML input could create special YAML input that allows
+      the attacker to run arbitrary Python code. This would allow the attacker
+      to steal files, download and install malware, or otherwise take over the
+      machine. Use `yaml.safe_load` or `yaml.SafeLoader` instead. blah blah.blah
