{"id":"DEBIAN-CVE-2026-103754","details":"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.","modified":"2026-10-02T05:01:06.594767929Z","published":"2026-10-01T12:17:15.937Z","upstream":["CVE-2026-103754"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-103754"}],"affected":[{"package":{"name":"ansible-runner","ecosystem":"Debian:12","purl":"pkg:deb/debian/ansible-runner?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.3.1-2","2.3.4-1","2.3.6-1","2.4.0-0.1","2.4.1-1","2.4.2+dfsg-1","2.4.3-1","2.4.3-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-103754.json"}},{"package":{"name":"ansible-runner","ecosystem":"Debian:13","purl":"pkg:deb/debian/ansible-runner?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.1-1","2.4.2+dfsg-1","2.4.3-1","2.4.3-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-103754.json"}},{"package":{"name":"ansible-runner","ecosystem":"Debian:14","purl":"pkg:deb/debian/ansible-runner?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.4.1-1","2.4.2+dfsg-1","2.4.3-1","2.4.3-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-103754.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:N/I:H/A:L"}]}
