CVE-2021-27191
The get-ip-range package before 4.0.0 for Node.js is vulnerable to denial of service (DoS) if the range is untrusted input.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.03%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
The get-ip-range package before 4.0.0 for Node.js is vulnerable to denial of service (DoS) if the range is untrusted input. An attacker could send a large range (such as 128.0.0.0/1) that causes resource exhaustion.
