CVE-2019-3881 — Insecure path handling in bundler — CVE Details

HIGH

Insecure path handling in Bundler

Published May 10, 2021Updated February 16, 2024Source: osv

Summary

Bundler prior to 2.1.0 uses a predictable path in `/tmp/`, created with insecure permissions as a storage location for gems, if locations under the user's home directory are not available. If Bundler is used in a scenario where the user does not have a writable home directory, an attacker could place malicious code in this directory that would be later loaded and executed.
