simple-git vulnerable to Remote Code Execution when enabling the ext transport protocolGHSA-9p95-fxvg-qgq2
HIGHFix: steveukx/git-js@7746480GHSA-9p95-fxvg-qgq2 is a high-severity (CVSS 8.1) OS Command Injection vulnerability in simple-git. 2 public exploit or proof-of-concept references are indexed, so weaponization risk is real. A fix is available for simple-git — see the affected versions and patch details below.
Exploitation Status
Proof-of-concept exploit code exists
- CISA’s SSVC triage found public proof-of-concept exploit code for this CVE, though no confirmed active exploitation.
- CISA assesses this as automatable — exploitation doesn’t require manual, per-target effort, which raises the odds of mass scanning and opportunistic attacks.
- A successful exploit gives an attacker total control of the affected component, not partial access.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for simple-git, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Fix
Update simple-git to 3.15.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-9p95-fxvg-qgq2 is resolved across your whole dependency graph.
Workarounds
Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
