| Description | A flaw was found in Data Science Pipelines (DSP). An attacker with namespace editor privileges can bypass security hardening by submitting a malicious Argo Workflow through the V1 API path. This allows the API server to create pods with elevated privileges, acting as a 'confused deputy' on behalf of the attacker. Successful exploitation grants the attacker node-root access, enabling arbitrary code execution and full control over the underlying node. |

Workarounds
CNA: To mitigate this issue, ensure that Data Science Project (DSP) namespaces enforce `pod-security.kubernetes.io/enforce: restricted`. Additionally, verify that the `pipeline-runner` ServiceAccount is not bound to `privileged` or `anyuid` Security Context Constraints (SCCs).
There are currently no legacy QID mappings associated with this CVE.
