CVE-2026-19706Red Hat Assisted Installer for Red Hat OpenShift Container Platform 2 missing authentication
CVE-2026-19706 is a missing authentication in Red Hat Assisted Installer for Red Hat OpenShift Container Platform 2, rated high (8.3 on CVSS 3.1).
Why this priority: High severity, with no exploitation signal yet.
Published · Updated · NVD status: Awaiting Analysis
What it is
A function that should require sign-in can be called by anyone.
How it is reached
An attacker can exploit it from the same local network segment, without an account, and nobody has to click anything. Success also depends on conditions the attacker does not fully control.
What an attacker gains
A successful attack can read the data it protects, change data or behaviour and take it offline. In practice, this kind of flaw lets an attacker act as a signed-in user, or an administrator, without valid credentials. The damage can spread past the vulnerable component into others.
Is it being exploited?
There is no public report of exploitation yet.
What to do
- No fixed version is listed yet. Find every place Red Hat Assisted Installer for Red Hat OpenShift Container Platform 2 runs, watch the references for a fix, and plan a replacement if it is no longer supported.
- Segment the networks that can reach it.
Description from NVD
During ABI bootstrap, the bootstrap node's approve-csr.service approves and signs every CSR without identity validation.
An attacker on the install network can retrieve the unauthenticated Ignition file (ports 22623/22624), extract a limited kubeconfig, submit a CSR for CN=system:admin, receive the signed certificate, and gain full cluster-admin access.
Exploitable only during the narrow bootstrap window.
What this means for your architecture.
A CVE names a product. Whether it matters depends on where that product sits in your systems: what reaches it, which trust boundary it guards and what it can reach once compromised. Veriom maps your components, their relationships and your trust boundaries from your code, cloud and delivery evidence, so you can see where a component like this sits. The radar itself does not look at your systems.
Components it touches
- Sign-in, session and token handling. The flaw sits between anonymous callers and authenticated sessions.
- Identity providers and SSO. The flaw sits between anonymous callers and authenticated sessions.
Trust boundaries in play
- Local network segment. The attacker must share a network segment with the target.
- Isolation between components. The impact crosses out of the vulnerable component into others it should be isolated from.
- Between anonymous callers and authenticated sessions. An attacker who crosses it can act as a signed-in user, or an administrator, without valid credentials.
Questions to answer about your own systems
- Where does Red Hat Assisted Installer for Red Hat OpenShift Container Platform 2 run in your systems, and at which version?
- Which network segments can reach them?
- What can it reach once compromised: which data stores, secrets and services?
