Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (4.47%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An exploitable vulnerability exists in the YAML loading functionality of util.py in OwlMixin before 2.0.0a12. A "Load YAML" string or file (aka load_yaml or load_yamlf) can execute arbitrary Python commands resulting in command execution because load is used where safe_load should have been used. An attacker can insert Python into loaded YAML to trigger this vulnerability.
