This may grant additional privileges to a container within the snap that were not originally intended.","published":"2024-06-21T20:15:11.000Z","lastModified":"2026-06-17T03:09:10.000Z","status":"Analyzed","sourceIdentifier":"security@ubuntu.com","cvss":{"version":"3.1","score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"},"cwe":["CWE-269"],"affected":["canonical/snapd","canonical/ubuntu linux"],"epss":{"score":0.00256,"percentile":0.1718,"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 (0.26%).
