{"id":"DEBIAN-CVE-2026-30892","details":"crun is an open source OCI Container Runtime fully written in C. In versions 1.19 through 1.26, the  `crun exec` option `-u` (`--user`) is incorrectly parsed. The value `1` is interpreted as UID 0 and GID 0 when it should have been UID 1 and  GID 0. The process thus runs with higher privileges than expected. Version 1.27 patches the issue.","modified":"2026-09-14T17:03:25.657315987Z","published":"2026-03-26T00:16:38.953Z","upstream":["CVE-2026-30892"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-30892"}],"affected":[{"package":{"name":"crun","ecosystem":"Debian:13","purl":"pkg:deb/debian/crun?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.21-1","1.21-2","1.21-3","1.24-1","1.26-1","1.27-1","1.27.1-1","1.28-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-30892.json"}},{"package":{"name":"crun","ecosystem":"Debian:14","purl":"pkg:deb/debian/crun?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.27-1"}]}],"versions":["1.21-1","1.21-2","1.21-3","1.24-1","1.26-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-30892.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"}]}
