# Mediary Scout: any logged-in user can make the server probe internal hosts

Link for people: https://infrastack.ai/live/CVE-2026-125359 (this .md is for agents)

Mediary Scout before 2026.11.05 lets any signed-in user, including non-owner accounts, set an arbitrary PanSou base URL without a role check. The server then sends POST requests to that URL, so an attacker can map internal hosts and ports through distinct error responses.

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

## How to check

- Check the installed Mediary Scout version against the fixed release in the product data (unknown from the sources given)
- Review whether non-owner accounts exist on the instance and can reach the savePanSouBaseUrlAction endpoint

## Fix

- Upgrade Mediary Scout to `2026.11.05` or later

## Timeline

## From the sources

Mediary Scout before 2026.11.05 contains a server-side request forgery vulnerability that allows any authenticated user, including non-owner accounts, to set an arbitrary PanSou base URL via savePanSouBaseUrlAction without role checks. Attackers can trigger probePanSou() to send server-side POST requests to internal hosts and use distinct error responses as an oracle for internal host and port discovery.
