{"id":"CVE-2025-55199","summary":"Helm Charts with Specific JSON Schema Values Can Cause Memory Exhaustion","details":"Helm is a package manager for Charts for Kubernetes. Prior to version 3.18.5, it is possible to craft a JSON Schema file in a manner which could cause Helm to use all available memory and have an out of memory (OOM) termination. This issue has been resolved in Helm 3.18.5. A workaround involves ensuring all Helm charts that are being loaded into Helm do not have any reference of $ref pointing to /dev/zero.","aliases":["BIT-helm-2025-55199","GHSA-9h84-qmv7-982p","GO-2025-3887"],"modified":"2026-04-10T04:16:08.841435Z","published":"2025-08-13T23:23:43.304Z","related":["CGA-gpwr-gp4r-hx6m","openSUSE-SU-2025:15469-1","openSUSE-SU-2026:10318-1","openSUSE-SU-2026:10319-1"],"database_specific":{"cna_assigner":"GitHub_M","unresolved_ranges":[{"extracted_events":[{"fixed":"3.18.5"}],"source":"AFFECTED_FIELD"}],"cwe_ids":["CWE-770"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/55xxx/CVE-2025-55199.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2025/55xxx/CVE-2025-55199.json"},{"type":"ADVISORY","url":"https://github.com/helm/helm/security/advisories/GHSA-9h84-qmv7-982p"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2025-55199"},{"type":"FIX","url":"https://github.com/helm/helm/commit/b78692c18f0fb38fe5ba4571a674de067a4c53a5"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/helm/helm","events":[{"introduced":"0"},{"fixed":"b78692c18f0fb38fe5ba4571a674de067a4c53a5"}],"database_specific":{"versions":[{"introduced":"0"},{"fixed":"3.18.5"}]}}],"versions":["1.999.0","v1.0","v1.1","v1.2","v2.0.0","v2.0.0-alpha.1","v2.0.0-alpha.2","v2.0.0-alpha.4","v2.0.0-alpha.5","v2.0.0-beta.1","v2.0.0-beta.2","v2.0.0-rc.1","v2.0.0-rc.2","v2.1.0","v2.2.0","v2.3.0","v2.4.0","v2.5.0","v2.6.0","v2.7.0","v2.7.0-rc1","v2.8.0-rc.1","v3.0.0-alpha.1","v3.0.0-alpha.2","v3.0.0-beta.1","v3.0.0-beta.2","v3.0.0-beta.3","v3.0.0-beta.4","v3.0.0-beta.5","v3.12.0-dev.1","v3.18.0","v3.18.0-rc.1","v3.18.0-rc.2","v3.18.1","v3.18.2","v3.18.3","v3.18.4"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2025-55199.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
