CVE-2026-118761: Kubeflow Pipelines decompression bomb in pipeline archive upload

Source: NVD(opens in a new tab)
Identifier: CVE-2026-118761
Published: October 29, 2026
Record updated: October 29, 2026

Known exploitation: Not listed in the CISA Known Exploited Vulnerabilities catalog at the last check.

Summary

Kubeflow Pipelines versions before 2.18.0 have a resource exhaustion flaw in the API server's handling of uploaded pipeline archives. A small ZIP or gzip-compressed tar file can expand to consume disproportionately large memory and exhaust API-server resources. Multipart pipeline and pipeline-version uploads decompress before namespace authorization, so a reachable caller does not need a successful pipeline-create authorization decision.

Mitigation

Fixed in 2.18.0.
