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.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H","score":7.4},"cwes":["CWE-400","CWE-770"],"references":["https://github.com/volcano-sh/volcano/security/advisories/GHSA-8wxp-xxp2-rcgx"],"products":["linuxfoundation:volcano"],"source":"nvd","synced_at":"2026-10-19T22:36:28.938604137+00:00"},"epss":{"cve":"CVE-2026-44247","score":0.00173,"percentile":0.06694,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-8wxp-xxp2-rcgx","url":"https://osv.dev/vulnerability/GHSA-8wxp-xxp2-rcgx","summary":"Volcano's webhook server vulnerable to OOM due to unbounded HTTP request body size","modified":"2026-06-25T19:56:24.208244977Z","packages":[{"ecosystem":"Go","name":"volcano.sh/volcano","purl":"pkg:golang/volcano.sh/volcano","ranges":["<1.12.4"],"fixed":["1.12.4"]},{"ecosystem":"Go","name":"volcano.sh/volcano","purl":"pkg:golang/volcano.sh/volcano","ranges":[">=1.13.0 <1.13.3"],"fixed":["1.13.3"]},{"ecosystem":"Go","name":"volcano.sh/volcano","purl":"pkg:golang/volcano.sh/volcano","ranges":[">=1.14.0 <1.14.2"],"fixed":["1.14.2"]}]},{"id":"GO-2026-5269","url":"https://osv.dev/vulnerability/GO-2026-5269","summary":"Volcano's webhook server vulnerable to OOM due to unbounded HTTP request body size in volcano.sh/volcano","modified":"2026-06-25T19:45:24.997231833Z","packages":[{"ecosystem":"Go","name":"volcano.sh/volcano","purl":"pkg:golang/volcano.sh/volcano","ranges":["<1.12.4",">=1.13.0 <1.13.3",">=1.14.0 <1.14.2"],"fixed":["1.12.4","1.13.3","1.14.2"]}]}],"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).
