# smart_proxy_dynflow: task console accepts certs from untrusted servers

Link for people: https://infrastack.ai/live/CVE-2026-107152 (this .md is for agents)

The task console in the smart_proxy_dynflow package accepts any client certificate signed by the Capsule's certificate authority without checking the list of trusted servers. An attacker holding such a certificate can read job details, including passwords passed to jobs, and cancel running tasks.

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

## Affected

- rubygems:smart_proxy_dynflow affected >= 0.4.0 fixed no fixed version listed

## How to check

On each Capsule/Smart Proxy, check the installed rubygem-smart_proxy_dynflow version (rpm -q rubygem-smart_proxy_dynflow or gem list smart_proxy_dynflow); 0.4.0 or later carries the flaw per the Red Hat bug. Also check the dynflow settings file for console_auth: true (the default); console_auth: false removes the check entirely.

## Fix

No fixed release yet. Red Hat says to apply the security update for Satellite/smart_proxy_dynflow when it is published (bug 2547374, deadline 2026-12-15).

## From the sources

An improper authentication vulnerability has been found in the task console in the smart_proxy_dynflow package. The console accepts any client certificate signed by the capsule's certificate authority. It does not check the list of servers the capsule trusts. A low-privileged network attacker or user must already hold such a certificate. They can open the console and read job details. Those details include passwords when a job was given them. They can also cancel a running task.
