The vulnerability allows remote attackers to bypass the library's built-in argument validation rules using conditional configuration includes and abbreviated Command Line Interface (CLI) options. By injecting custom arguments into Git execution pipelines, an attacker can force the application to load a malicious local configuration file, resulting in arbitrary OS command execution under the privileges of the parent Node.js process.\n\n## TL;DR\nA flaw in simple-git permits attackers to inject malicious arguments via conditional Git configuration rules (includeIf) and abbreviated CLI options, leading to remote code execution.\n\n## Exploit Status: POC\n\n## Technical Details\n\n- **CWE ID**: CWE-77, CWE-78\n- **Attack Vector**: Network\n- **CVSS v3.1 Score**: 8.1\n- **EPSS Score**: 0.0046 (Percentile: 37.65%)\n- **Exploit Status**: poc\n- **CISA KEV Status**: Not Listed\n\n## Affected Systems\n\n- simple-git\n- @simple-git/argv-parser\n- @simple-git/args-pathspec\n- **simple-git**: < 4.0.0 (Fixed in: `4.0.0`)\n- **@simple-git/argv-parser**: < 1.1.1 (Fixed in: `1.1.1`)\n- **@simple-git/args-pathspec**: < 1.0.4 (Fixed in: `1.0.4`)\n\n## Mitigation\n\n- Upgrade simple-git to version 4.0.0 or higher immediately.\n- Avoid passing custom or user-influenced command-line arguments to lower-level execution APIs.\n- Cleanse and restrict the runtime execution environment of the Node.js application process.\n\n**Remediation Steps:**\n1. Update the project dependencies using your package manager: npm install simple-git@latest or yarn upgrade simple-git.\n2. Audit the codebase to identify usage of raw CLI input fields mapped to simple-git methods.\n3. Deploy process-level logging to capture spawned Git binary arguments in production environments.\n\n## References\n\n- [Fix Commit](https://github.com/steveukx/git-js/commit/98864c678444d9336357c844efa4fd5a7984c0d7)\n- [GitHub Security Advisory](https://github.com/steveukx/git-js/security/advisories/GHSA-g4wm-2vf7-vfgr)\n- [NVD Vulnerability Details](https://nvd.nist.gov/vuln/detail/CVE-2026-102826)\n\n\n---\n*Generated by [CVEReports](https://cvereports.com/reports/CVE-2026-102826) - Automated Vulnerability Intelligence*", "creation_timestamp": "2026-10-06T06:30:32.000000Z"} 2026-10-06T06:30:32+00:00 https://vulnerability.circl.lu/sighting/05fb7c6f-3c09-4014-a128-3d4865c2e967/export 2026-10-07T03:36:35.950348+00:00 Automation user https://cvepremium.circl.lu/user/automation {"uuid": "05fb7c6f-3c09-4014-a128-3d4865c2e967", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "9f56dd64-161d-43a6-b9c3-555944290a09", "vulnerability": "CVE-2026-102826", "type": "seen", "source": "https://bsky.app/profile/thehackerwire.bsky.social/post/3mwomp2w6br2d", "content": "\ud83d\udfe0 CVE-2026-102826 - High (8.1)\n\nsimple-git, an interface for running git commands in any node.js application, enables application...\n\nhttps://www.thehackerwire.com/vulnerability/CVE-2026-102826/\n\n#infosec #cybersecurity #CVE #vulnerability #security #patchstack", "creation_timestamp": "2026-09-29T20:02:39.573606Z"} 2026-09-29T20:02:39.573606+00:00 https://vulnerability.circl.lu/sighting/29176c8b-6d55-4c72-86bc-ad9b6cbe24bf/export 2026-10-07T03:36:35.950688+00:00 Joseph Lee https://cvepremium.circl.lu/user/syspect {"uuid": "29176c8b-6d55-4c72-86bc-ad9b6cbe24bf", "vulnerability_lookup_origin": "1a89b78e-f703-45f3-bb86-59eb712668bd", "author": "86ecb4e1-bb32-44d5-9f39-8a4673af8385", "vulnerability": "CVE-2026-102826", "type": "published-proof-of-concept", "source": "https://github.com/steveukx/git-js/security/advisories/GHSA-g4wm-2vf7-vfgr", "content": "", "creation_timestamp": "2026-09-26T07:42:47.000000Z"} 2026-09-26T07:42:47+00:00
