GHSA-28xr-mwxg-3qc8 is a high-severity (CVSS 8.1) CWE-88 vulnerability in simple-git. 1 public exploit reference exists, so weaponization risk is real. A fix is available for simple-git — see the affected versions and patch details below.

EPSS Exploitation Probability
EPSS (Exploit Prediction Scoring System) is a daily probability model maintained by FIRST.org. It estimates the likelihood a CVE will be exploited in production environments within the next 30 days, derived from real-world threat intelligence signals.
How urgent is this, really
GHSA-28xr-mwxg-3qc8 plotted by exploitation likelihood (EPSS) against impact (CVSS). The shaded corner — EPSS 50%+ and CVSS 7.0+ — is where this CVE doesn't sit, though severity or exploitability alone can still warrant action.
Where this sits among everything scored
Of 379,145 CVEs with a current EPSS score, this one falls in the < 10% band (highlighted). Real counts from FIRST.org, not a sample — log-scaled since the landscape is heavily right-skewed.
Real-World Exposure
How broadly this vulnerability is actually deployed: weekly install volume shows current usage, and reverse-dependency count shows how many other packages break if it stays unpatched.
simple-gitnpmDescription
simple-git (maintained as git-js named repository on GitHub) is a light weight interface for running git commands in any node.js application.The package simple-git before 3.5.0 are vulnerable to Command Injection due to an incomplete fix of CVE-2022-24433 which only patches against the git fetch attack vector. A similar use of the --upload-pack feature of git is also supported for git clone, which the prior fix didn't cover. A fix was released in [email protected].

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 3.5.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-28xr-mwxg-3qc8 is resolved across your whole dependency graph.
Workarounds
If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
How O3 protects you
O3 Security's impact-aware SCA analyses which vulnerable code paths your application actually calls, so a match like GHSA-28xr-mwxg-3qc8 can be triaged on real exposure rather than presence alone.
Tailored to GHSA-28xr-mwxg-3qc8. Runtime protection reduces exposure until a permanent patch is applied and verified — it complements patching, it doesn't replace it.
Frequently Asked Questions
Is GHSA-28xr-mwxg-3qc8 in your dependencies?
O3 Security finds GHSA-28xr-mwxg-3qc8 across npm dependencies, including transitive ones, and its impact-aware SCA ranks findings by whether your code actually calls the vulnerable path.
