A race condition flaw was found in ansible-runner, where an attacker could watch for rapid creation and deletion of a temporary directory, substitute their directory at that name, and then have access to ansible-runner's private_data_dir the next time ansible-runner made use of the private_data_dir. The highest Threat out of this flaw is to integrity and confidentiality.

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.
