KubeAI — Vulnerability (CVE-2026-34940)
Date: 2026-04
Affected: kubeai/kubeai
Attack vector: command-injection
Category: vulnerability-disclosure
Severity: High
CVE: CVE-2026-34940
CWE: CWE-78
CVSS: 8.7 (CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:N)

KubeAI is an AI inference operator for kubernetes. Prior to 0.23.2, the ollamaStartupProbeScript() function in internal/modelcontroller/engine_ollama.go constructs a shell command string using fmt.Sprintf with unsanitized model URL components (ref, modelParam). This shell command is executed via bash -c as a Kubernetes startup probe. An attacker who can create or update Model custom resources can inject arbitrary shell commands that execute inside model server pods. This vulnerability is fixed in 0.23.2.
