GHSA-4859-gpc7-4j66
GHSA-4859-gpc7-4j66 is a remote code execution vulnerability in dot. O3 Security confirms whether GHSA-4859-gpc7-4j66 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Command Injection in dot
Blast Radius
dotReal-time download stats are indexed for npm and PyPI packages. This vulnerability affects npm packages — download data is not available via public APIs for these ecosystems.
Description
All versions of dot are vulnerable to Command Injection. The template compilation may execute arbitrary commands if an attacker can inject code in the template or if a Prototype Pollution-like vulnerability can be exploited to alter an Object's prototype.
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | dot | all versions | No fix |
Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for dot. 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.
Remediation status
No patched version of dot has shipped for GHSA-4859-gpc7-4j66 yet. Where your build allows, override or pin the dependency away from the vulnerable range, and apply any maintainer-recommended mitigation.
Mitigate without a patch
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-4859-gpc7-4j66 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-4859-gpc7-4j66. 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-4859-gpc7-4j66 in your dependencies?
O3 detects GHSA-4859-gpc7-4j66 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
