Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Kubeflow Pipelines (Go module github.com/kubeflow/pipelines) versions through 0.0.0-20260831164314-ba9ae72cc860 are affected. A caller who can reach the multipart pipeline or pipeline-version upload endpoints can send a small compressed archive that expands to a large amount of data, exhausting API-server memory and interrupting service; the decompression happens before namespace authorization, so no create permission is needed. Upgrade to 0.0.0-20260831164314-ba9ae72cc860 or later. Until then, restrict access to upload and import endpoints.
