CVE-2021-3702

Estado: ModificadaMedia (6.3)—

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.
