{"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":"2026-09-17T03:47:17.213647824Z","published":"2026-09-15T19:45:07.836Z","database_specific":{"cwe_ids":["CWE-281"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/88xxx/CVE-2026-88922.json","cna_assigner":"HashiCorp"},"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":"fab8735a6a69ee6b8c87c647255288cfa49154a7"}],"database_specific":{"source":"AFFECTED_FIELD","extracted_events":[{"introduced":"1.0.1"},{"fixed":"2.2.4"}]}}],"versions":["cmd/go-getter/v2.2.3","s3/v2.2.3","gcs/v2.2.3","v2.2.3","cmd/go-getter/v2.2.2","s3/v2.2.2","gcs/v2.2.2","v2.2.2","s3/v2.2.1","gcs/v2.2.1","cmd/go-getter/v2.2.1","v2.2.1","cmd/go-getter/v2.2.0","s3/v2.2.0","gcs/v2.2.0","v2.2.0","s3/v2.1.1","gcs/v2.1.1","cmd/go-getter/v2.1.1","v2.1.1","s3/v2.1.0","gcs/v2.1.0","v2.1.0","v2.0.2","s3/v2.0.2","gcs/v2.0.2","cmd/go-getter/v2.0.2","v2.0.1","v2.0.0","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/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"}]}
