CVE-2020-26222 Information

Description

Dependabot is a set of packages for automated dependency management for Ruby JavaScript Python PHP Elixir Rust Java .NET Elm and Go. In Dependabot-Core from version 0.119.0.beta1 before version 0.125.1 there is a remote code execution vulnerability in dependabot-common and dependabot-go_modules when a source branch name contains malicious injectable bash code. For example if Dependabot is configured to use the following source branch name: /$(curl127.0.0.1)\ Dependabot will make a HTTP request to the following URL: 127.0.0.1 when cloning the source repository. The fix was applied to version 0.125.1. As a workaround one can escape the branch name prior to passing it to the Dependabot::Source class.
