{"id":"CVE-2026-88922","summary":"Go-getter vulnerable to a privilege escalation issue in its archive decompression handling","details":"The go-getter library up to versions 1.8.8 and 2.2.3 is vulnerable to a privilege escalation issue in its archive decompression handling that may allow a crafted archive to cause extracted files to be created with elevated permission bits. Where extraction is performed by a privileged user, this may allow a local actor to obtain the privileges of the extracting process. This vulnerability (CVE-2026-88922) is fixed in go-getter 1.8.9 and 2.2.4.","modified":"2026-10-05T18:12:02.879783746Z","published":"2026-09-15T19:45:07.836Z","related":["SUSE-SU-2026:4444-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/88xxx/CVE-2026-88922.json","cna_assigner":"HashiCorp","cwe_ids":["CWE-281"]},"references":[{"type":"WEB","url":"https://discuss.hashicorp.com/t/hcsec-2026-39-go-getter-vulnerable-to-a-privilege-escalation-issue-in-its-archive-decompression-handling/77752"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/88xxx/CVE-2026-88922.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-88922"},{"type":"PACKAGE","url":"https://github.com/hashicorp/go-getter"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/hashicorp/go-getter","events":[{"introduced":"dde89f93975670ed3a449be055954c139e36810f"},{"fixed":"8d08b7a9750d4d5d61d0d6693a5ac85f0318dc30"}],"database_specific":{"extracted_events":[{"introduced":"1.0.1"},{"fixed":"1.8.9"}],"source":"AFFECTED_FIELD"}}],"versions":["v1.8.8","v1.8.7","v1.8.6","v1.8.5","v1.8.4","v1.8.3","v1.8.2","v1.8.1","v1.8.0","v1.7.9","v1.7.8","v1.7.7","v1.7.6","v1.7.5","v1.7.4","v1.7.3","v1.7.2","v1.7.1","v1.7.0","v1.6.2","v1.6.1","v1.6.0","v1.5.11","v1.5.10","v1.5.9","v1.5.8","v1.5.7","v1.5.6","v1.5.5","v1.5.4","v1.5.3","v1.5.2","v1.5.1","v1.5.0","v1.4.2","v1.4.1","v1.4.0","v1.1.0","v1.3.0","v1.2.0","v1.0.3","v1.0.2","v1.0.1"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-88922.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:H"}]}
