{"apiVersion":"1.0","identifier":"CVE-2026-62313","description":"Incus is a system container and virtual machine manager. Prior to version 7.3.0, project-level enforcement of `restricted.containers.privilege=isolated` can be trivially bypassed, allowing a user to create a non-isolated (shared host idmap) container in a project that is configured to forbid them. The restriction only rejects an explicitly set `security.idmap.isolated=false` (or empty) and fails to enforce anything when the key is omitted entirely. Because an unset `security.idmap.isolated` defaults to `false` (non-isolation), a user simply leaves the key out and obtains exactly the container state the restriction is meant to forbid. This defeats the tenant-isolation guarantee the restriction exists to provide. Containers in the project share the host uid/gid map instead of receiving unique, non-overlapping ranges, weakening the isolation boundary between co-tenant containers and the host. Version 7.3.0 patches the issue.","publishedAt":"2026-08-21T15:16:45","lastModifiedAt":"2026-08-26T18:16:43","sourceUrl":"https://nvd.nist.gov/vuln/detail/CVE-2026-62313","cvssScore":4.3,"cvssVector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:L","epssProbability":0.00213,"riskScore":0.44,"affectedProduct":"Incus","affectedVersions":"<7.3.0","vulnerabilityType":"Critical software","operatingSystems":[],"links":{"self":"https://www.redsauce.net/api/cves/CVE-2026-62313","webPages":{"es":"https://www.redsauce.net/es/cves/CVE-2026-62313","en":"https://www.redsauce.net/en/cves/CVE-2026-62313","fr":"https://www.redsauce.net/fr/cves/CVE-2026-62313","pt":"https://www.redsauce.net/pt/cves/CVE-2026-62313","de":"https://www.redsauce.net/de/cves/CVE-2026-62313","sk":"https://www.redsauce.net/sk/cves/CVE-2026-62313","el":"https://www.redsauce.net/el/cves/CVE-2026-62313"},"source":"https://nvd.nist.gov/vuln/detail/CVE-2026-62313"}}
