{"id":"DEBIAN-CVE-2026-50163","details":"oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2, ensureLinkPath in content/file/utils.go:262-275 validates a hardlink target relative to the extract base but returns the unresolved target, causing os.Link(\"victim.secret\", \"\u003cextract_base\u003e/payload.tar.gz/evil_cwd_link\") to resolve header.Linkname against the process current working directory for a Typeflag=TypeLink entry such as Name=payload.tar.gz/evil_cwd_link and Linkname=\"victim.secret\" with io.deis.oras.content.unpack: \"true\", which can expose or tamper with files such as .env, .git/config, .aws/credentials, and ~/.ssh/config. This issue is fixed in version 2.6.2.","modified":"2026-08-27T23:06:27.272580783Z","published":"2026-07-17T20:17:23.943Z","upstream":["CVE-2026-50163"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-50163"}],"affected":[{"package":{"name":"golang-oras-oras-go","ecosystem":"Debian:12","purl":"pkg:deb/debian/golang-oras-oras-go?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.1-1","2.5.0-1","2.6.0-1","2.6.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-50163.json"}},{"package":{"name":"golang-oras-oras-go","ecosystem":"Debian:13","purl":"pkg:deb/debian/golang-oras-oras-go?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.5.0-1","2.6.0-1","2.6.2-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-50163.json"}},{"package":{"name":"golang-oras-oras-go","ecosystem":"Debian:14","purl":"pkg:deb/debian/golang-oras-oras-go?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.2-1"}]}],"versions":["2.5.0-1","2.6.0-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-50163.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:L/A:N"}]}
