What is CVE-2026-103754?
CVE-2026-103754 is a medium-severity path traversal vulnerability in Red Hat Ansible Automation Platform 2, published on 1 Oct 2026. Any signed-in user can exploit it over the network, with no action from the victim.
Official description
A flaw was found in ansible-runner. 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.
Weakness: CWE-22
