{"id":"CVE-2022-31080","aliases":["GHSA-6wvc-6pww-qr4r","GO-2022-0512"],"url":"https://o3.security/vulnerability/CVE-2022-31080","summary":"KubeEdge Websocket Client in package Viaduct: DoS from large response message","details":"### Impact\nA large response received by the viaduct WSClient can cause a DoS from memory exhaustion. The entire body of the response is being read into memory which could allow an attacker to send a request that returns a response with a large body.\nThe consequence of the exhaustion is that the process which invokes a WSClient will be in a denial of service. It will be affected If users which are authenticated to the edge side and connect from the edge side to `cloudhub` through WebSocket protocol.\n\n### Patches\nThis bug has been fixed in Kubeedge 1.11.1, 1.10.2, 1.9.4. Users should update to these versions to resolve the issue.\n\n### Workarounds\nAt the time of writing, no workaround exists.\n\n### References\nNA\n\n### Credits\nThanks David Korczynski and Adam Korczynski of ADA Logics for responsibly disclosing this issue in accordance with the [kubeedge security policy](https://github.com/kubeedge/kubeedge/security/policy) during a security audit sponsored by CNCF and facilitated by OSTIF.\n\n### For more information\nIf you have any questions or comments about this advisory:\n* Open an issue in [KubeEdge repo](https://github.com/kubeedge/kubeedge/issues/new/choose)\n* To make a vulnerability report, email your vulnerability to the private [cncf-kubeedge-security@lists.cncf.io](mailto:cncf-kubeedge-security@lists.cncf.io) list with the security details and the details expected for [KubeEdge bug reports](https://github.com/kubeedge/kubeedge/blob/master/.github/ISSUE_TEMPLATE/bug-report.md).\n","published":"2022-07-11T20:55:09Z","modified":"2026-08-12T03:51:28.364962269Z","cvss":{"score":4.4,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:H/UI:N/S:U/C:N/I:N/A:H"},"epss":null,"cisaKev":null,"exploitsKnown":0,"affectedPackages":[{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","fixedVersion":"1.11.1"},{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","fixedVersion":"1.10.2"},{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","fixedVersion":"1.9.4"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/31xxx/CVE-2022-31080.json"},{"type":"ADVISORY","url":"https://github.com/kubeedge/kubeedge/security/advisories/GHSA-6wvc-6pww-qr4r"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-31080"},{"type":"PACKAGE","url":"github.com/kubeedge/kubeedge"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-08-12T03:51:28.364962269Z"}}
