{"id":"BIT-helm-2022-36049","summary":"Flux2 Helm Controller denial of service","details":"Flux2 is a tool for keeping Kubernetes clusters in sync with sources of configuration, and Flux's helm-controller is a Kubernetes operator that allows one to declaratively manage Helm chart releases. Helm controller is tightly integrated with the Helm SDK. A vulnerability found in the Helm SDK that affects flux2 v0.0.17 until v0.32.0 and helm-controller v0.0.4 until v0.23.0 allows for specific data inputs to cause high memory consumption. In some platforms, this could cause the controller to panic and stop processing reconciliations. In a shared cluster multi-tenancy environment, a tenant could create a HelmRelease that makes the controller panic, denying all other tenants from their Helm releases being reconciled. Patches are available in flux2 v0.32.0 and helm-controller v0.23.0.","aliases":["BIT-flux-2022-36049","CVE-2022-36049","GHSA-p2g7-xwvr-rrw3"],"modified":"2025-12-02T23:43:09.098351Z","published":"2024-03-06T10:53:31.970Z","database_specific":{"severity":"High","cpes":["cpe:2.3:a:helm:helm:*:*:*:*:*:*:*:*"]},"references":[{"type":"WEB","url":"https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=44996"},{"type":"WEB","url":"https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=48360"},{"type":"WEB","url":"https://github.com/fluxcd/flux2/security/advisories/GHSA-p2g7-xwvr-rrw3"},{"type":"WEB","url":"https://github.com/helm/helm/security/advisories/GHSA-7hfp-qfw3-5jxh"},{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36049"}],"affected":[{"package":{"name":"helm","ecosystem":"Bitnami","purl":"pkg:bitnami/helm"},"ranges":[{"type":"SEMVER","events":[{"introduced":"3.0.0"},{"fixed":"3.9.4"}]}],"database_specific":{"source":"https://github.com/bitnami/vulndb/tree/main/data/helm/BIT-helm-2022-36049.json"},"severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}],"schema_version":"1.7.3"}
