Security Bulletin
Summary
HashiCorp go-getter versions before 1.8.10 and go-getter/v2 versions before 2.2.5 are vulnerable to path traversal during S3 and GCS directory downloads, which may allow files to be written outside the requested destination. This vulnerability (CVE-2026-19585) is fixed in go-getter 1.8.10 and go-getter/v2 2.2.5.
Vulnerability Details
CVEID: CVE-2026-19585
DESCRIPTION: S3 and GCS directory downloads did not ensure that each listed object’s destination remained within the requested directory. An attacker who can influence an object name in a bucket that an application retrieves in directory mode may cause files to be written outside that destination, subject to the downloader’s filesystem permissions. Single-object downloads are not affected.

Disclaimer
According to the Forum of Incident Response and Security Teams (FIRST), the Common Vulnerability Scoring System (CVSS) is an "industry open standard designed to convey vulnerability severity and help to determine urgency and priority of response." IBM PROVIDES THE CVSS SCORES ""AS IS"" WITHOUT WARRANTY OF ANY KIND, INCLUDING THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. CUSTOMERS ARE RESPONSIBLE FOR ASSESSING THE IMPACT OF ANY ACTUAL OR POTENTIAL SECURITY VULNERABILITY. In addition to other efforts to address potential vulnerabilities, IBM periodically updates the record of components contained in our product offerings. As part of that effort, if IBM identifies previously unidentified packages in a product/service inventory, we address relevant vulnerabilities regardless of CVE date. Inclusion of an older CVEID does not demonstrate that the referenced product has been used by IBM since that date, nor that IBM was aware of a vulnerability as of that date. We are making clients aware of relevant vulnerabilities as we become aware of them. "Affected Products and Versions" referenced in IBM Security Bulletins are intended to be only products and versions that are supported by IBM and have not passed their end-of-support or warranty date. Thus, failure to reference unsupported or extended-support products and versions in this Security Bulletin does not constitute a determination by IBM that they are unaffected by the vulnerability. Reference to one or more unsupported versions in this Security Bulletin shall not create an obligation for IBM to provide fixes for any unsupported or extended-support products or versions.
