CVE-2017-16618: Owlmixin Project Owlmixin

Critical severity, CVSS 9.8. EPSS: 4.5% chance of exploitation in the next 30 days.

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.

Affected products

• Owlmixin Project Owlmixin: before 2.0.0 (fixed in 2.0.0); version 2.0.0 only
