The manipulation of those files can change the behavior of the starter-suid program when instances are joined resulting in potential privilege escalation on the host.","published":"2019-05-14T21:29:01.000Z","lastModified":"2026-06-17T02:12:43.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-732"],"affected":["sylabs/singularity","fedoraproject/fedora","opensuse/backports","opensuse/leap"],"epss":{"score":0.02088,"percentile":0.81496,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (2.09%).
