{"id":"CVE-2020-26222","aliases":["GHSA-23f7-99jx-m54r"],"url":"https://o3.security/vulnerability/CVE-2020-26222","summary":"Remote code execution in dependabot-core branch names when cloning","details":"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: \"/$({curl,127.0.0.1})\", 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.","published":"2020-11-13T16:15:18.277Z","modified":"2026-07-09T14:06:18.571539Z","cvss":{"score":8.8,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"RubyGems","name":"dependabot-omnibus","fixedVersion":"0.125.1"},{"ecosystem":"RubyGems","name":"dependabot-common","fixedVersion":"0.125.1"}],"fix":{"url":"https://github.com/dependabot/dependabot-core/commit/e089116abbe284425b976f7920e502b8e83a61b5","label":"dependabot/dependabot-core@e089116"},"references":[{"type":"FIX","url":"https://github.com/dependabot/dependabot-core/commit/e089116abbe284425b976f7920e502b8e83a61b5"},{"type":"FIX","url":"https://github.com/dependabot/dependabot-core/pull/2727"},{"type":"EVIDENCE","url":"https://github.com/dependabot/dependabot-core/security/advisories/GHSA-23f7-99jx-m54r"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T14:06:18.571539Z"}}
