CVE-2026-47237

HIGHPre-NVD 8.08.0—
EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.0 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.4%, top 65% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Kubeflow Community Distribution helps users to install Kubeflow Platform in popular Kubernetes clusters. Prior to version 26.03-rc.1, a Kubeflow setup based on the official manifests or most other packaged Kubeflow distributions is vulnerable to authorization token stealing from any user of the Kubeflow UI or APIs, such as the Dashboard, Pipelines API, or Notebooks. With this token, the attacker can take over the user's account and the data that is processed by that user. The attacker needs a valid user with the `kubeflow-edit` role / Contributor role in a random Kubeflow namespace to perform this attack. This is given if _Automatic Profile Creation_ is enabled. Version 26.03-rc.1 fixes the issue.
