CVE-2021-3702: ansible-runner 2.0.0 vulnerable to Race Condition
(updated )
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.
