Affected packages
• PyPI pyanyapi: < 0.6.1 → fixed in 0.6.1
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.
