{"id":"CVE-2026-63296","summary":"Project restriction bypass via instance migration config override","details":"An authorization bypass vulnerability in LXD allows an authenticated attacker to bypass target project restrictions during instance migration. When migrating an instance to a target project, LXD accepts configuration overrides without validating the new configuration against the target project's enforced restrictions. An attacker can exploit this flaw to move instances with disallowed high-privilege configurations into restricted projects, bypassing security controls.","aliases":["GHSA-gcr9-5q6r-w625"],"modified":"2026-08-15T11:31:08.096563178Z","published":"2026-08-12T19:27:45.736Z","database_specific":{"unresolved_ranges":[{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"6.0"},{"fixed":"6.10"}]}],"cna_assigner":"canonical","cwe_ids":["CWE-863"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63296.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/63xxx/CVE-2026-63296.json"},{"type":"ADVISORY","url":"https://github.com/canonical/lxd/security/advisories/GHSA-gcr9-5q6r-w625"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-63296"},{"type":"PACKAGE","url":"https://github.com/canonical/lxd"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/canonical/lxd","events":[{"introduced":"1e1349e3cbf30c1b2ce74e531d4dd0fd52c45be1"},{"fixed":"58b58151cfc3bd9fb0fedce26fcdd73a3e67bdb8"},{"introduced":"761d134ceabd306f57acfb0ca51f59b03751a5b0"},{"fixed":"c6146714d0cacd04b77598bac149f5db714834f6"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"5.0.0"},{"fixed":"5.0.8"},{"introduced":"5.21.0"},{"fixed":"5.21.6"}]}}],"versions":["lxd-5.0.7","lxd-5.21.5","lxd-5.17","lxd-5.16","lxd-5.15","lxd-5.14","lxd-5.13","lxd-5.12","lxd-5.11","lxd-5.0.2","lxd-5.10","lxd-5.9","lxd-5.8","lxd-5.7","lxd-5.6","lxd-5.5","lxd-5.0.1","lxd-5.4","lxd-5.3","lxd-5.2","lxd-5.1","lxd-5.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-63296.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H"}]}
