{"id":"CVE-2022-23524","aliases":["BIT-helm-2022-23524","GHSA-6rx9-889q-vv2r","GO-2022-1167"],"url":"https://o3.security/vulnerability/CVE-2022-23524","summary":"Helm vulnerable to Denial of service through string value parsing","details":"Fuzz testing, by Ada Logics and sponsored by the CNCF, identified input to functions in the _strvals_ package that can cause a stack overflow. In Go, a stack overflow cannot be recovered from. Applications that use functions from the _strvals_ package in the Helm SDK can have a Denial of Service attack when they use this package and it panics.\n\n### Impact\n\nThe _strvals_ package contains a parser that turns strings into Go structures. For example, the Helm client has command line flags like `--set`, `--set-string`, and others that enable the user to pass in strings that are merged into the values. The _strvals_ package converts these strings into structures Go can work with. Some string inputs can cause array data structures to be created causing a stack overflow.\n\nApplications that use the _strvals_ package in the Helm SDK to parse user supplied input can suffer a Denial of Service when that input causes a panic that cannot be recovered from.\n\nThe Helm Client will panic with input to `--set`, `--set-string`, and other value setting flags that causes a stack overflow. Helm is not a long running service so the panic will not affect future uses of the Helm client.\n\n### Patches\n\nThis issue has been resolved in 3.10.3. \n\n### Workarounds\n\nSDK users can validate strings supplied by users won't create large arrays causing significant memory usage before passing them to the _strvals_ functions.\n\n### For more information\n\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\n\nDisclosed by Ada Logics in a fuzzing audit sponsored by CNCF.","published":"2022-12-15T00:28:34.540Z","modified":"2026-08-12T03:51:32.863208494Z","cvss":{"score":5.3,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"helm.sh/helm/v3","fixedVersion":"3.10.3"}],"fix":{"url":"https://github.com/helm/helm/commit/3636f6824757ff734cb265b8770efe48c1fb3737","label":"helm/helm@3636f68"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/23xxx/CVE-2022-23524.json"},{"type":"ADVISORY","url":"https://github.com/helm/helm/security/advisories/GHSA-6rx9-889q-vv2r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-23524"},{"type":"WEB","url":"https://github.com/helm/helm/commit/3636f6824757ff734cb265b8770efe48c1fb3737"},{"type":"PACKAGE","url":"https://github.com/helm/helm"},{"type":"WEB","url":"https://pkg.go.dev/vuln/GO-2022-1167"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:32.863208494Z"}}
