CVE-2026-103754 PUBLISHED

Ansible-runner: ansible-runner: path traversal and symlink escape in unstream_dir() allows file write outside the target directory

Assigner: redhat
Reserved: 01.10.2026 Published: 01.10.2026 Updated: 01.10.2026

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.
