GHSA-3f95-r44v-8mrg
HIGHGHSA-3f95-r44v-8mrg is a high-severity (CVSS 8.1) CWE-88 vulnerability in simple-git. O3 Security confirms whether GHSA-3f95-r44v-8mrg is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.

Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
simple-gitnpmDescription
The package simple-git before 3.3.0 is vulnerable to Command Injection via argument injection. When calling the .fetch(remote, branch, handlerFn) function, both the remote and branch parameters are passed to the git fetch subcommand. By injecting some git options, it was possible to get arbitrary command execution.

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for simple-git. O3's reachability analysis confirms whether the vulnerable code path is actually invoked in your application, so you act on real exposure instead of every transitive match.
Fix
Update simple-git to 3.3.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-3f95-r44v-8mrg 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 pinpoints whether GHSA-3f95-r44v-8mrg is reachable in your code and exactly where to fix it, then blocks exploitation in production at runtime until the patched version is deployed.
Tailored to GHSA-3f95-r44v-8mrg. 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-3f95-r44v-8mrg in your dependencies?
O3 detects GHSA-3f95-r44v-8mrg across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
