GHSA-753c-phhg-cj29
Fix: pahen/madge@da5cbc9GHSA-753c-phhg-cj29 is a SQL Injection vulnerability in madge. 1 public exploit reference exists, so weaponization risk is real. O3 Security confirms whether GHSA-753c-phhg-cj29 is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Madge vulnerable to command injection
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.
madgenpmDescription
This affects the package madge before 4.0.1. It is possible to specify a custom Graphviz path via the graphVizPath option parameter which, when the .image(), .svg() or .dot() functions are called, is executed by the childprocess.exec function.
PoC
const madge = require('madge');
madge('..', {graphVizPath: "touch HELLO;"}) .then((res) => res.svg()) .then((writtenImagePath) => { console.log('Image written to ' + writtenImagePath); });

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for madge. 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 madge to 4.0.1 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-753c-phhg-cj29 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-753c-phhg-cj29 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-753c-phhg-cj29. 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-753c-phhg-cj29 in your dependencies?
O3 detects GHSA-753c-phhg-cj29 across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
