# VPN gateway getVpnData function allows SQL injection, exposing all stored data

Link for people: https://infrastack.ai/live/CVE-2026-40820 (this .md is for agents)

An unauthenticated remote attacker with high privileges can inject SQL through the getVpnData function, because special characters in a SELECT command are not neutralized. The sources say a successful attack can cause a total loss of confidentiality.

_Summary, check and fix written by a model from the sources; labelled as such._
