A flaw was found in ansible-runner where the default temporary files configuration in ansible-2.0.0 are written to world R/W locations. This flaw allows an attacker to pre-create the directory, resulting in reading private information or forcing ansible-runner to write files as the legitimate user in a place they did not expect. The highest threat from this vulnerability is to confidentiality and integrity.
