CVE-2026-15218: Models-as-a-service: red hat openshift ai: maas-api and maas-controller serviceaccounts with excessive permissions lead to privilege escalation

Noroxi assessment

Priority: Monitor (action score 31/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.70% (FIRST EPSS); higher than 53.2% of all records.
  • Anyone who can reach it over the internet can trigger it. Administrator privileges are required. No user action is required. Special conditions such as timing or configuration are required.
  • Fixed version: github.com/opendatahub-io/models-as-a-service maas-api d7099eabc2c52bb5328cb7a9dd137cc2ea90dd53.

Low priority for now. Upgrade to github.com/opendatahub-io/models-as-a-service maas-api d7099eabc2c52bb5328cb7a9dd137cc2ea90dd53 or later.

Primary sources: NVD · CVE.org · FIRST EPSS

A flaw was found in the maas-api and maas-controller ServiceAccounts within Red Hat OpenShift AI. These ServiceAccounts are granted cluster-wide permissions that exceed their operational requirements. An attacker who compromises the identity of these ServiceAccounts, either through a remote code execution vulnerability or by creating a malicious pod in the same namespace, could exploit these excessive permissions. This could lead to full cluster administrator privileges through the creation of new ClusterRoleBindings or the disclosure of sensitive information by accessing all secrets across the cluster.
