{"id":"AZL-10900","summary":"CVE-2022-36049 affecting package helm for versions less than 3.9.4-2","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.","modified":"2026-04-01T05:06:34.292120Z","published":"2022-09-07T21:15:08Z","upstream":["CVE-2022-36049"],"references":[{"type":"WEB","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-36049"}],"affected":[{"package":{"name":"helm","ecosystem":"Azure Linux:2","purl":"pkg:rpm/azure-linux/helm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.9.4-2"}]}],"database_specific":{"source":"https://github.com/microsoft/AzureLinuxVulnerabilityData/blob/main/osv/AZL-10900.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
