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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","score":8.8},"cwes":["CWE-74"],"references":["https://github.com/dependabot/dependabot-core/commit/e089116abbe284425b976f7920e502b8e83a61b5","https://github.com/dependabot/dependabot-core/pull/2727","https://github.com/dependabot/dependabot-core/security/advisories/GHSA-23f7-99jx-m54r","https://github.com/dependabot/dependabot-core/commit/e089116abbe284425b976f7920e502b8e83a61b5","https://github.com/dependabot/dependabot-core/pull/2727"],"products":["dependabot_project:dependabot"],"source":"nvd","synced_at":"2026-10-19T21:11:20.317016139+00:00"},"epss":{"cve":"CVE-2020-26222","score":0.03088,"percentile":0.87709,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-23f7-99jx-m54r","url":"https://osv.dev/vulnerability/GHSA-23f7-99jx-m54r","summary":"Remote code execution in dependabot-core branch names when cloning","modified":"2026-07-08T06:29:09.252313036Z","packages":[{"ecosystem":"RubyGems","name":"dependabot-omnibus","purl":"pkg:gem/dependabot-omnibus","ranges":[">=0.119.0.beta1 <0.125.1"],"fixed":["0.125.1"]},{"ecosystem":"RubyGems","name":"dependabot-common","purl":"pkg:gem/dependabot-common","ranges":[">=0.119.0.beta1 <0.125.1"],"fixed":["0.125.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
