Prior to version 7.1.0, `(*backend).CreateInstanceFromBackup` in `internal/server/storage/backend.go` contains a nil-pointer dereference that an authenticated user with permission to create instances in any project can trigger remotely by uploading a crafted backup tarball. The Incus daemon panics and the process crashes, causing denial of service to every project on that cluster member. This is a sibling of `GHSA-fwj8-62r8-8p8m`, `GHSA-r7w7-mmxr-47r9`, and `GHSA-x5r6-jr56-89pv` (all assigned 2026-05-04). Those patches added guards on adjacent fields of the same `backup/config.Config` struct; the `Volume` field on the instance-import path was missed. Version 7.1.0 contains an updated patch.","state":0,"publishedAt":"2026-08-21T14:14:12.28+00:00","modifiedAt":"2026-08-21T14:39:55.034+00:00","affected":[{"ecosystem":"Vendor product","name":"incus","ranges":[],"versions":[],"rawVersionEvidence":"{\n                    \"vendor\": \"lxc\",\n                    \"product\": \"incus\",\n                    \"versions\": [\n                        {\n                            \"version\": \"< 7.1.0\",\n                            \"status\": \"affected\"\n                        }\n                    ]\n                }"}],"metrics":[{"system":"CVSS 4.0","vector":"CVSS:4.0/AV:L/AC:L/AT:P/PR:L/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U","score":4.4,"severity":"MEDIUM"}],"references":["https://github.com/lxc/incus/security/advisories/GHSA-8g7m-96c8-8wwc","https://github.com/lxc/incus/commit/98e64f0a6fcfdc9676eea0246418d490c53297bf"],"sourceUrl":"https://www.cve.org/CVERecord?id=CVE-2026-47753","license":"CVE Program Terms of Use","key":"cve-program:CVE-2026-47753","identifiers":["CVE-2026-47753"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
