PyYAML insecurely deserializes YAML strings leading to arbitrary code execution
In PyYAML before 5.1, the yaml.load() API could execute arbitrary code. In other words, yaml.safe_load is not used.
This was intended to be fixed in 4.1, but due to breaking changes, 4.1 was yanked and 5.1 contains the patch for CVE-2017-18342.
