CVE-2026-44247
Published:May 27, 2026
Updated:June 13, 2026
Volcano is a Kubernetes-native batch scheduling system. Prior to v1.14.2, v1.13.3, and v1.12.4, the Volcano webhook server does not enforce a size limit on incoming HTTP request bodies. Any in-cluster pod that can reach the webhook endpoint may send an arbitrarily large request body, potentially causing the webhook server to be killed by OOM. All Volcano deployments with the webhook server exposed to in-cluster traffic are affected. This vulnerability is fixed in v1.14.2, v1.13.3, and v1.12.4.
