An authenticated project operator in a restricted multi-tenant environment can bypass policy restrictions by importing a maliciously crafted instance backup containing restricted configuration keys within a snapshot. When the snapshot is restored, these restricted keys are applied to the live instance without policy validation. Starting the modified instance grants the operator unauthorized host root access."}],"affected":[{"vendor":"Canonical","product":"LXD","packageName":"LXD","platforms":["Linux"],"repo":"https://github.com/canonical/lxd","defaultStatus":"unaffected","versions":[{"version":"5.21.0","status":"affected","versionType":"semver","lessThan":"5.21.5"},{"version":"5.0.0","status":"affected","versionType":"semver","lessThan":"5.0.7"},{"version":"6.0","status":"affected","versionType":"semver","lessThan":"6.9"}]}],"problemTypes":[{"descriptions":[{"lang":"en","description":"CWE-863: Incorrect Authorization","cweId":"CWE-863","type":"CWE"}]}],"references":[{"url":"https://github.com/canonical/lxd/security/advisories/GHSA-ppq7-4492-5552","tags":["vdb-entry","vendor-advisory"]},{"url":"https://github.com/canonical/lxd/pull/18301","tags":["patch"]},{"url":"https://github.com/canonical/lxd/pull/18303","tags":["patch"]},{"url":"https://github.com/canonical/lxd/pull/18304","tags":["patch"]}],"impacts":[{"capecId":"CAPEC-153","descriptions":[{"lang":"en","value":"CAPEC-153: Input Data Manipulation"}]}],"metrics":[{"format":"CVSS","scenarios":[{"lang":"en","value":"GENERAL"}],"cvssV3_1":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"HIGH","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH","baseScore":7.2,"baseSeverity":"HIGH"}}],"source":{"discovery":"EXTERNAL"},"solutions":[{"lang":"en","value":"Upgrade to LXD version 6.9 or later, 5.21.5 or later, or 5.0.7 or later."}],"credits":[{"lang":"en","type":"finder","value":"Miha Purg"}],"providerMetadata":{"orgId":"cc1ad9ee-3454-478d-9317-d3e869d708bc","shortName":"canonical","dateUpdated":"2026-06-26T15:50:38.453Z"}},"adp":[{"references":[{"url":"https://github.com/canonical/lxd/security/advisories/GHSA-ppq7-4492-5552","tags":["exploit"]}],"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-26T00:00:00+00:00","options":[{"Exploitation":"poc"},{"Automatable":"no"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3","id":"CVE-2026-9640"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-30T03:55:24.628Z"}}]}}
