CVE-2026-13717
Rhoai maas: llm-d: maas/llm-d inference gateway: default allowedroutes.namespaces.from: all allows namespace users to hijack shared model-serving traffic (tokens, prompts, outputs)
Description
A flaw was found in the Red Hat OpenShift AI (RHOAI) MaaS Gateway. Improper configuration of the Gateway in a model-serving context allows a standard user with low privileges to intercept, read, log, and alter all MaaS model traffic. This includes sensitive information such as access keys, input prompts, and outputs, leading to significant information disclosure and data tampering.
