CVE-2021-3701
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.
Does this matter?
Lower severity and a low EPSS score (0.29%). Track it; it rarely justifies an emergency change on its own.
