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."}],"affected":[{"vendor":"Red Hat","product":"Red Hat Ansible Automation Platform 2","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"ansible-automation-platform-27/controller-rhel9","defaultStatus":"affected","cpes":["cpe:/a:redhat:ansible_automation_platform:2"]},{"vendor":"Red Hat","product":"Red Hat Ansible Automation Platform 2","collectionURL":"https://access.redhat.com/downloads/content/package-browser/","packageName":"automation-controller","defaultStatus":"affected","cpes":["cpe:/a:redhat:ansible_automation_platform:2"]}],"references":[{"url":"https://access.redhat.com/security/cve/CVE-2026-103754","tags":["vdb-entry","x_refsource_REDHAT"]},{"url":"https://bugzilla.redhat.com/show_bug.cgi?id=2544510","name":"RHBZ#2544510","tags":["issue-tracking","x_refsource_REDHAT"]},{"url":"https://github.com/ansible/ansible-runner/pull/1550"}],"datePublic":"2026-09-11T00:00:00.000Z","problemTypes":[{"descriptions":[{"cweId":"CWE-22","description":"Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')","lang":"en","type":"CWE"}]}],"x_redhatCweChain":"CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')","timeline":[{"lang":"en","time":"2026-09-11T00:00:00.000Z","value":"Reported to Red Hat."},{"lang":"en","time":"2026-09-11T00:00:00.000Z","value":"Made public."}],"credits":[{"lang":"en","value":"Red Hat would like to thank Liqiang Ji (SQUARE Research Group, Institute of Software, Chinese Academy of Sciences (ISCAS)) for reporting this issue."}],"providerMetadata":{"orgId":"53f830b8-0a3f-465b-8143-3b8a9948e749","shortName":"redhat","dateUpdated":"2026-10-01T17:16:23.179Z"},"x_generator":{"engine":"cvelib 1.8.0"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-10-01T13:20:19.192040Z","id":"CVE-2026-103754","options":[{"Exploitation":"none"},{"Automatable":"no"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-10-01T13:20:30.126Z"}}]}}
