This vulnerability allows unauthorized access to internal network resources by manipulating DNS responses, posing a risk to systems that rely on this plugin for webhook functionality. Organizations using the Grav API plugin should prioritize updating to the latest version to mitigate potential exploitation.

Original NVD Description

Grav API plugin before 1.0.16 contains a server-side request forgery vulnerability in webhook delivery that allows attackers to bypass hostname validation by DNS rebinding. Attackers controlling authoritative DNS for a configured webhook hostname can answer validation lookups with public addresses and delivery lookups with private addresses to reach internal network resources.
