TL;DR
Affected versions of this package validate restricted outbound URLs only at pre-flight, leaving a window where the hostname can be re-resolved to a private address at connection time. An attacker-controlled DNS server can use this DNS rebinding behavior to make notification and webhook clients reach internal services.
Who does this affect?
You are affected if you are using a version that falls within the vulnerable range.
