{"cve":"CVE-2025-32777","nvd":{"published":"2025-04-30T19:15:55.353","modified":"2026-06-17T09:12:33.383","status":"Deferred","description":"Volcano is a Kubernetes-native batch scheduling system. Prior to versions 1.11.2, 1.10.2, 1.9.1, 1.11.0-network-topology-preview.3, and 1.12.0-alpha.2, attacker compromise of either the Elastic service or the extender plugin can cause denial of service of the scheduler. This is a privilege escalation, because Volcano users may run their Elastic service and extender plugins in separate pods or nodes from the scheduler. In the Kubernetes security model, node isolation is a security boundary, and as such an attacker is able to cross that boundary in Volcano's case if they have compromised either the vulnerable services or the pod/node in which they are deployed. The scheduler will become unavailable to other users and workloads in the cluster. The scheduler will either crash with an unrecoverable OOM panic or freeze while consuming excessive amounts of memory. This issue has been patched in versions 1.11.2, 1.10.2, 1.9.1, 1.11.0-network-topology-preview.3, and 1.12.0-alpha.2.","cvss_v4":{"vector":"CVSS:4.0/AV:N/AC:H/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","score":8.2},"cvss_v3":null,"cwes":["CWE-770"],"references":["https://github.com/volcano-sh/volcano/releases/tag/v1.10.2","https://github.com/volcano-sh/volcano/releases/tag/v1.11.0-network-topology-preview.3","https://github.com/volcano-sh/volcano/releases/tag/v1.11.2","https://github.com/volcano-sh/volcano/releases/tag/v1.12.0-alpha.2","https://github.com/volcano-sh/volcano/releases/tag/v1.9.1"],"products":[],"source":"nvd","synced_at":"2026-10-19T22:01:11.054312287+00:00"},"epss":{"cve":"CVE-2025-32777","score":0.0048,"percentile":0.41395,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-hg79-fw4p-25p8","url":"https://osv.dev/vulnerability/GHSA-hg79-fw4p-25p8","summary":"Volcano Scheduler Denial of Service via Unbounded Response from Elastic Service/extender Plugin","modified":"2025-05-06T19:12:07Z","packages":[{"ecosystem":"Go","name":"volcano.sh/volcano","purl":"pkg:golang/volcano.sh/volcano","ranges":["<1.9.1"],"fixed":["1.9.1"]},{"ecosystem":"Go","name":"volcano.sh/volcano","purl":"pkg:golang/volcano.sh/volcano","ranges":[">=1.10.0-alpha.0 <1.10.2"],"fixed":["1.10.2"]},{"ecosystem":"Go","name":"volcano.sh/volcano","purl":"pkg:golang/volcano.sh/volcano","ranges":[">=1.11.0-network-topology-preview.0 <1.11.0-network-topology-preview.3"],"fixed":["1.11.0-network-topology-preview.3"]},{"ecosystem":"Go","name":"volcano.sh/volcano","purl":"pkg:golang/volcano.sh/volcano","ranges":[">=1.11.0 <1.11.2"],"fixed":["1.11.2"]},{"ecosystem":"Go","name":"volcano.sh/volcano","purl":"pkg:golang/volcano.sh/volcano","ranges":[">=1.12.0-alpha.0 <1.12.0-alpha.2"],"fixed":["1.12.0-alpha.2"]}]},{"id":"GO-2025-3656","url":"https://osv.dev/vulnerability/GO-2025-3656","summary":"Volcano Scheduler Denial of Service via Unbounded Response from Elastic Service/extender Plugin in volcano.sh/volcano","modified":"2026-03-03T04:56:33.011798Z","packages":[{"ecosystem":"Go","name":"volcano.sh/volcano","purl":"pkg:golang/volcano.sh/volcano","ranges":["<1.9.1",">=1.10.0-alpha.0 <1.10.2",">=1.11.0-network-topology-preview.0 <1.11.0-network-topology-preview.3",">=1.11.0 <1.11.2",">=1.12.0-alpha.0 <1.12.0-alpha.2"],"fixed":["1.9.1","1.10.2","1.11.0-network-topology-preview.3","1.11.2","1.12.0-alpha.2"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
