Security readout for executives and security teams
Plain-English summary
CVE-2026-6951 is a critical remote code execution issue in simple-git before 3.36.0. The risk matters when an application lets untrusted users influence options passed into simple-git. In that situation, an attacker may cause the server or automation process to run unintended code.
Executive priority
Treat this as urgent for internet-facing or multi-user systems that use simple-git. Prioritize dependency upgrades and exposure validation because successful exploitation could compromise confidentiality, integrity, and availability of the running service.
Technical view
The flaw is an incomplete fix for CVE-2022-25912. simple-git blocked one dangerous option form but missed the equivalent --config form. Sources describe possible RCE when untrusted input reaches the options argument and is combined with Git configuration that enables external protocol handling.
Likely exposure
Exposure is most likely in Node.js or WebJars-based applications using simple-git before 3.36.0, especially repository import, CI, developer portal, automation, or admin workflows that pass user-controlled values into simple-git options.
Exploitation context
The bundle lists CVSS 9.8 and exploit maturity as proof-of-concept, and includes a public gist reference. KEV is false, and the supplied sources do not establish active exploitation in the wild.
Researcher notes
Focus triage on call sites that expose simple-git option parameters to external input. Do not assume every simple-git installation is exploitable; the described condition requires untrusted input reaching the options argument.
Mitigation direction
- Upgrade simple-git to 3.36.0 or later.
- Update or remove org.webjars.npm:simple-git if present.
- Prevent untrusted input from reaching simple-git options.
- Review vendor advisories for package-specific remediation guidance.
Validation and detection
- Inventory direct and transitive simple-git dependencies.
- Confirm deployed versions are 3.36.0 or later.
- Search code for user-controlled values passed to simple-git options.
- Review repository import and automation workflows using simple-git.

CWE-88: Command execution behavior lookup
Command injection weaknesses can lead defenders to review execution techniques and command interpreter telemetry. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
Open ATT&CK lookupCWE-94: Code execution behavior lookup
Code execution and unsafe deserialization weaknesses often justify reviewing execution behavior and process telemetry. Open the exact CWE lookup page first, then review the ATT&CK searches from that MITRE weakness context. This is a Glexia lookup hint, not an official ATT&CK mapping.
