HIGH7.0EPSS 0.15%Insecure path handling in Bundler
Published: 5/10/2021Modified: 2/16/2024
Also known as:GHSA-g98m-96g9-wfjq
Description
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.
Affected packages (1)
- RubyGems/bundler>= 1.14.0, < 2.1.0
