Description

An issue was discovered in StaticPool in SUCHMOKUO node-worker-threads-pool version 1.4.3 that allows attackers to cause a denial of service.

This can be mitigated by manually creating a timeout. For example:

const { StaticPool } = require(\"node-worker-threads-pool\");
	
	const staticPool = new StaticPool({
 size: 1,
 task: (n) => {
 while (n) {
 console.log(\"a\");
 }
 return n;
 }
});
 
 staticPool.createExecutor().setTimeout(10).exec(1).then((result) => {
 console.log(\"result from thread pool:\", result);
}).catch(() => console.error('timeout'));

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
