CVE-2026-123059Eclipse BaSyx Helm Charts cleartext storage of sensitive data
CVE-2026-123059 is a cleartext storage of sensitive data in Eclipse BaSyx Helm Charts, rated high (7.5 on CVSS 3.1).
Why this priority: High severity, with no exploitation signal yet.
Published · Updated · NVD status: Received
What it is
Sensitive data is stored unencrypted where others can read it. Credentials are stored or sent in a way others can recover.
How it is reached
An attacker can exploit it over the network, with an ordinary user 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 sign in with credentials the vendor shipped or stored unprotected.
Is it being exploited?
There is no public report of exploitation yet. EPSS estimates a 0.21% chance of exploitation activity in the next 30 days, higher than 11% of scored CVEs.
What to do
- No fixed version is listed yet. Find every place Eclipse BaSyx Helm Charts runs, watch the references for a fix, and plan a replacement if it is no longer supported.
- While there is no fix, review who holds accounts that can reach it.
Description from NVD
In Eclipse BaSyx Helm Charts version 2.2.0 of the `aas-basyx-v2-full` chart, deployments with the bundled Keycloak enabled store the client secret of the `basyx-technical-user` OAuth2 client in cleartext in a Kubernetes ConfigMap. This client uses the client-credentials grant and its service account holds the realm `admin` role.
The chart correctly writes `keycloak.technicalUser.clientSecret` to a Kubernetes Secret, but the template `basyx-keycloak-realm.yaml` also substitutes the same value into the Keycloak realm-import JSON, which is stored in the ConfigMap `<keycloak.fullnameOverride>-realm`. A principal that can read ConfigMaps but not Secrets in the release namespace, such as a holder of the built-in Kubernetes `view` ClusterRole, can read the client secret from the ConfigMap. They can then exchange it at the Keycloak token endpoint for an access token with the `admin` role. That token grants full create, read, update, delete and execute rights on all BaSyx repositories and registries in the deployment.
The bundled Keycloak is disabled by default. No fixed release of the `aas-basyx-v2-full` chart exists. Affected users should migrate to the `basyx` chart, or deploy without the bundled Keycloak and rotate the `basyx-technical-user` client secret.
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
- Credentials kept in code, configuration, images or firmware. The flaw sits between a stored secret and anyone who can read where it is kept.
Trust boundaries in play
- Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
- Between a stored secret and anyone who can read where it is kept. An attacker who crosses it can sign in with credentials the vendor shipped or stored unprotected.
Questions to answer about your own systems
- Where does Eclipse BaSyx Helm Charts run in your systems, and at which version?
- Which of those instances can be reached from the internet or partner networks?
- What can it reach once compromised: which data stores, secrets and services?
