{"id":"GHSA-5xqw-8hwv-wg92","summary":"Helm Allows A Specially Crafted JSON Schema To Cause A Stack Overflow","details":"A Helm contributor discovered that a specially crafted JSON Schema within a chart can lead to a stack overflow.\n\n### Impact\nA JSON Schema file within a chart can be crafted with a deeply nested chain of references, leading to parser recursion that can exceed the stack size limit and trigger a stack overflow. \n\n### Patches\nThis issue has been resolved in Helm v3.17.3.\n\n### Workarounds\nEnsure that the JSON Schema within any charts loaded by Helm does not have a large number of nested references. These JSON Schema files are larger than 10 MiB.\n\n### For more information\nHelm's security policy is spelled out in detail in our [SECURITY](https://github.com/helm/community/blob/master/SECURITY.md) document.\n\n### Credits\nDisclosed by Jakub Ciolek at AlphaSense.","aliases":["BIT-helm-2025-32387","CVE-2025-32387","GO-2025-3602"],"modified":"2026-02-04T03:23:25.467394Z","published":"2025-04-10T13:48:31Z","related":["CGA-42hx-875p-8r28"],"database_specific":{"severity":"MODERATE","cwe_ids":["CWE-121","CWE-674"],"github_reviewed_at":"2025-04-10T13:48:31Z","github_reviewed":true,"nvd_published_at":"2025-04-09T23:15:37Z"},"references":[{"type":"WEB","url":"https://github.com/helm/helm/security/advisories/GHSA-5xqw-8hwv-wg92"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-32387"},{"type":"WEB","url":"https://github.com/helm/helm/commit/d8ca55fc669645c10c0681d49723f4bb8c0b1ce7"},{"type":"PACKAGE","url":"https://github.com/helm/helm"}],"affected":[{"package":{"name":"helm.sh/helm/v3","ecosystem":"Go","purl":"pkg:golang/helm.sh/helm/v3"},"ranges":[{"type":"SEMVER","events":[{"introduced":"0"},{"fixed":"3.17.3"}]}],"database_specific":{"source":"https://github.com/github/advisory-database/blob/main/advisories/github-reviewed/2025/04/GHSA-5xqw-8hwv-wg92/GHSA-5xqw-8hwv-wg92.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
