CVE-2017-16616
Unsafe pyyaml load usage in PyAnyAPI
Severity by source
Trivy's own label is CRITICAL. Rated critical by NVD, GHSA.
Description
An exploitable vulnerability exists in the YAML parsing functionality in the YAMLParser method in Interfaces.py in PyAnyAPI before 0.6.1. A YAML parser 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.
