CVE-2026-80435IBM DataStage on Cloud Pak for Data XML external entity
CVE-2026-80435 is a XML external entity in IBM DataStage on Cloud Pak for Data, rated medium (5.0 on CVSS 3.1).
Why this priority: Medium severity, with no exploitation signal.
Published · Updated · NVD status: Analyzed
What it is
The XML parser resolves external entities, so a crafted document can read local files or reach internal hosts.
How it is reached
An attacker can exploit it over the network, with an ordinary user account, and nobody has to click anything.
What an attacker gains
The direct impact is limited: partial access to data or a partial outage. In practice, this kind of flaw lets an attacker read local files or reach internal hosts through the parser. 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 IBM DataStage on Cloud Pak for Data 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
IBM DataStage on Cloud Pak for Data 5.4.0.0 could allow a remote authenticated attacker to obtain sensitive information due to an XML external entity (XXE) injection flaw.
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
- XML and document parsers in APIs and import features. The flaw sits between uploaded or posted documents and the service parsing them.
Trust boundaries in play
- Authenticated network access. An account is needed, so exposure follows who can sign in: customers, partners or staff.
- Isolation between components. The impact crosses out of the vulnerable component into others it should be isolated from.
- Between uploaded or posted documents and the service parsing them. An attacker who crosses it can read local files or reach internal hosts through the parser.
Questions to answer about your own systems
- Where does IBM DataStage on Cloud Pak for Data 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?
