Ansible before 1.6.7 does not prevent inventory data with {{ and lookup substrings, and does not prevent remote data with {{ substrings, which allows remote attackers to execute arbitrary code via (1) crafted lookup(pipe) calls or (2) crafted Jinja2 data.

Weakness

The product constructs all or part of a command, data structure, or record using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify how it is parsed or interpreted when it is sent to a downstream component.
