{"id":"GHSA-7j4w-x8x8-5mvg","summary":"Assisted Migration Agent: Path traversal in gzipped tarball handling enables arbitrary file write and remote code execution","details":"A flaw was found in assisted-migration-agent. An unauthenticated attacker, located on the same local area network (LAN), can exploit a path traversal vulnerability. By crafting a specially designed gzipped tarball, the attacker can bypass security checks and write arbitrary files to the system. This could ultimately lead to the execution of unauthorized code on the appliance.","aliases":["CVE-2026-53476","GO-2026-6231"],"modified":"2026-08-18T15:10:32.533217842Z","published":"2026-06-10T15:31:33Z","database_specific":{"github_reviewed_at":"2026-08-14T19:21:11Z","nvd_published_at":"2026-06-10T15:16:42Z","cwe_ids":["CWE-22","CWE-59"],"severity":"CRITICAL","github_reviewed":true},"references":[{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53476"},{"type":"WEB","url":"https://github.com/kubev2v/assisted-migration-agent/pull/256"},{"type":"WEB","url":"https://github.com/kubev2v/assisted-migration-agent/commit/bcae0438ad8386321a300413d71c982a11b7b5b7"},{"type":"WEB","url":"https://access.redhat.com/security/cve/CVE-2026-53476"},{"type":"WEB","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2487233"},{"type":"PACKAGE","url":"https://github.com/kubev2v/assisted-migration-agent"}],"affected":[{"package":{"name":"github.com/kubev2v/assisted-migration-agent","ecosystem":"Go","purl":"pkg:golang/github.com/kubev2v/assisted-migration-agent"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"0.16.0"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2026/06/GHSA-7j4w-x8x8-5mvg/GHSA-7j4w-x8x8-5mvg.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
