What is CVE-2026-88922?

The Go-Getter library, utilized for downloading files and managing archives, contains a vulnerability that affects its archive decompression handling. This flaw can be exploited to escalate privileges, where a specially crafted archive can lead to extracted files being created with elevated permissions. Specifically, if extraction is executed by a user with privileges, a local actor could gain access to the privileges of that user, posing a significant security risk. The issue has been addressed in Go-Getter versions 1.8.9 and 2.2.4, making it crucial for users to upgrade to these versions to mitigate potential threats.

Affected Version(s)
