CVE-2017-16615
An exploitable vulnerability exists in the YAML parsing functionality in the parse_yaml_query method in parser.py in MLAlchemy before 0.2.2.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.45%). 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 parsing functionality in the parse_yaml_query method in parser.py in MLAlchemy before 0.2.2. When processing YAML-Based queries for data, 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.
