The unstream_dir() function, which receives and extracts a streamed zip archive on the worker side of the ansible-runner transmit/worker protocol, re-creates symbolic links from archive content without validating the link target and applies chmod() and utime() to an unsanitized filesystem path derived from the archive member name. A crafted archive processed by a worker that consumes attacker-influenced input can create files, create symbolic links, or change permissions outside the intended target directory, which can be leveraged toward code execution."

As an additional measure, ensuring that only the trusted automation-controller produces the transmit stream consumed by ansible-runner workers (the standard authenticated Ansible Automation Platform topology) limits exposure to this flaw."
