Description
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.

Impact

The go-getter library is vulnerable in its handling of archive decompression up to versions 1.8.8 and 2.2.3. A crafted archive can cause extracted files to be created with elevated permission bits the extraction, a local attacker could cause files to be written with those higher privileges, allowing the attacker to obtain the extracting process’s permissions.

Affected Systems

The vulnerability affects HashiCorp’s shared go-getter library in the versions listed above. Organizations using any of these releases should verify whether they rely on the go-getter archive extraction routine in a privileged context.

Risk and Exploitability

The CVSS score of 6.7 indicates a moderate severity, while the EPSS score of less than 1% suggests low likelihood of exploitation in the current environment. The issue is not listed in the CISA KEV catalog. Exploitation requires local access to a system where a privileged user runs go-getter to extract an archive. A crafted archive is the main vector, and the problem arises when decompression writes files with elevated permission bits, enabling privilege escalation.

Remediation

No solution or workaround provided in the CVE record.

OpenCVE Recommended Actions

  • Update go-getter to version 1.8.9 or 2.2.4 to address the archive decompression privilege escalation flaw
  • Run any archive extraction routines under the lowest possible privilege; avoid executing go-getter as root or an administrator
  • Configure file system permissions or use access control policies to prevent permission bits from the archive
