Improper parsing of octal bytes in netmask
Quick fix
GHSA-4c7m-wxvm-r7gc — netmask: upgrade to the fixed version with the command below.

Improper input validation of octal strings in netmask npm package v1.0.6 and below allows unauthenticated remote attackers to perform indeterminate SSRF, RFI, and LFI attacks on many of the dependent packages. A remote unauthenticated attacker can bypass packages relying on netmask to filter IPs and reach critical VPN or LAN hosts.
