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."}], "lastModified": "2026-04-15T21:17:27.010", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:kubeai:kubeai:*:*:*:*:*:kubernetes:*:*", "vulnerable": true, "matchCriteriaId": "81310778-51DF-4D61-9DA1-73EAC537BDCF", "versionEndExcluding": "0.23.2"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
