CVE-2026-88922 Details
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.
A privilege escalation vulnerability has been identified in the HashiCorp Go-getter library, affecting versions prior to 1.8.8 and 2.2.3. The issue arises from the library's handling of archive decompression, where extracted files can be created with elevated permission bits. This vulnerability allows a local actor to gain the privileges of the user performing the extraction, particularly if the extraction is done by a privileged user.
Users are advised to upgrade to Go-getter versions 1.8.9 or 2.2.4. After upgrading, be aware that files extracted from archives will only retain standard read, write, and execute permissions. Applications that previously relied on archives to provide additional permission bits may experience a change in behavior.
