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.","published":"2026-06-10T13:55:44.144Z","modified":"2026-10-28T02:31:02.315480640Z","cvss":{"score":9.6,"severity":"CRITICAL","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/kubev2v/assisted-migration-agent","fixedVersion":"0.16.0"}],"fix":{"url":"https://github.com/kubev2v/assisted-migration-agent/pull/256","label":"kubev2v/assisted-migration-agent#256"},"references":[{"type":"ADVISORY","url":"https://access.redhat.com/security/cve/CVE-2026-53476"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/53xxx/CVE-2026-53476.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-53476"},{"type":"REPORT","url":"https://bugzilla.redhat.com/show_bug.cgi?id=2487233"},{"type":"FIX","url":"https://github.com/kubev2v/assisted-migration-agent/pull/256"},{"type":"PACKAGE","url":"https://github.com/kubev2v/assisted-migration-agent"},{"type":"WEB","url":"https://github.com/kubev2v/assisted-migration-agent/commit/bcae0438ad8386321a300413d71c982a11b7b5b7"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-10-28T02:31:02.315480640Z"}}
