CVE-2026-34940

HIGH

KubeAI has an OS Command Injection via Model URL in Ollama Engine startup probe allows arbitrary command execution in model pods

Title source: cna
STIX 2.1

Description

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.
