CVE-2026-88922: CWE-281: Improper Preservation of Permissions in HashiCorp Shared library
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.
AI Analysis
Technical Summary
The go-getter library up to versions 1.8.8 and 2.2.3 contains a privilege escalation vulnerability due to improper preservation of permissions during archive decompression. This flaw allows a crafted archive to cause extracted files to be created with elevated permission bits. When extraction is performed by a privileged user, a local attacker can leverage this to gain the privileges of the extracting process. The vulnerability is tracked as CVE-2026-88922 and is fixed in go-getter versions 1.8.9 and 2.2.4.
Potential Impact
This vulnerability can lead to local privilege escalation if a privileged user extracts a maliciously crafted archive, allowing an attacker to gain elevated permissions equivalent to the extracting process. The CVSS score of 6.7 reflects a medium severity with high impact on confidentiality, integrity, and availability, but requires local access and user interaction.
Mitigation Recommendations
A fix is available in go-getter versions 1.8.9 and 2.2.4. Users should upgrade to these or later versions to remediate this vulnerability. No additional vendor advisory was provided, so patch status is confirmed by the version fix information in the description.
