{"id":"DEBIAN-CVE-2026-55686","details":"Podman is a tool for managing OCI containers and pods. From 3.0.0 until 5.7.1, running a malicious container image where the WORKDIR path contains a symlink can create a directory or modify ownership on the host filesystem. Modified ownership is less likely to happen as that requires help from an untrusted/malicious process that mutates the host filesystem tree during dereferencing of the WORKDIR path, to trigger a race condition. This vulnerability is fixed in 5.7.1.","modified":"2026-08-27T23:06:17.053295115Z","published":"2026-06-26T17:16:34.330Z","upstream":["CVE-2026-55686"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-55686"}],"affected":[{"package":{"name":"podman","ecosystem":"Debian:13","purl":"pkg:deb/debian/podman?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["5.4.2+ds1-2","5.6.1+ds1-1","5.6.1+ds1-2","5.6.1+ds2-2","5.6.1+ds2-3","5.6.2+ds1-1","5.6.2+ds1-2","5.6.2+ds1-3","5.6.2+ds1-3+exp1","5.6.2+ds1-4","5.7.0+ds2-1","5.7.0+ds2-2","5.7.0+ds2-3","5.8.0+ds1-1","5.8.1+ds1-1","5.8.1+ds1-2","5.8.1+ds1-3","5.8.2+ds1-1","5.8.2+ds1-2","5.8.2+ds1-3","5.8.3+ds1-1","5.8.4+ds1-1","5.8.4+ds1-2","5.8.6+ds1-1","5.8.6+ds1-2"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-55686.json"}},{"package":{"name":"podman","ecosystem":"Debian:14","purl":"pkg:deb/debian/podman?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"5.8.1+ds1-2"}]}],"versions":["5.4.2+ds1-2","5.6.1+ds1-1","5.6.1+ds1-2","5.6.1+ds2-2","5.6.1+ds2-3","5.6.2+ds1-1","5.6.2+ds1-2","5.6.2+ds1-3","5.6.2+ds1-3+exp1","5.6.2+ds1-4","5.7.0+ds2-1","5.7.0+ds2-2","5.7.0+ds2-3","5.8.0+ds1-1","5.8.1+ds1-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2026-55686.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"}]}
