{"cve":"CVE-2022-31080","nvd":{"published":"2022-07-11T21:15:08.383","modified":"2026-06-17T04:44:45.223","status":"Modified","description":"KubeEdge is an open source system for extending native containerized application orchestration capabilities to hosts at Edge. Prior to versions 1.11.1, 1.10.2, and 1.9.4, a 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. The consequence of the exhaustion is that the process which invokes a WSClient will be in a denial of service. The software is affected If users who are authenticated to the edge side connect to `cloudhub` from the edge side through WebSocket protocol. This bug has been fixed in Kubeedge 1.11.1, 1.10.2, and 1.9.4. There are currently no known workarounds.","cvss_v4":null,"cvss_v3":{"version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H","score":6.5},"cwes":["CWE-770","CWE-400"],"references":["https://github.com/kubeedge/kubeedge/security/advisories/GHSA-6wvc-6pww-qr4r","https://github.com/kubeedge/kubeedge/security/advisories/GHSA-6wvc-6pww-qr4r"],"products":["linuxfoundation:kubeedge"],"source":"nvd","synced_at":"2026-10-19T21:33:44.859608815+00:00"},"epss":{"cve":"CVE-2022-31080","score":0.00723,"percentile":0.54047,"date":"2026-10-31"},"kev":null,"osv":[{"id":"GHSA-6wvc-6pww-qr4r","url":"https://osv.dev/vulnerability/GHSA-6wvc-6pww-qr4r","summary":"DoS in KubeEdge's Websocket Client in package Viaduct","modified":"2024-08-21T15:41:42.873574Z","packages":[{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","ranges":[">=1.11.0 <1.11.1"],"fixed":["1.11.1"]},{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","ranges":[">=1.10.0 <1.10.2"],"fixed":["1.10.2"]},{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","ranges":["<1.9.4"],"fixed":["1.9.4"]}]},{"id":"GO-2022-0512","url":"https://osv.dev/vulnerability/GO-2022-0512","summary":"DoS in KubeEdge's Websocket Client in package Viaduct in github.com/kubeedge/kubeedge","modified":"2026-03-03T04:50:30.040572Z","packages":[{"ecosystem":"Go","name":"github.com/kubeedge/kubeedge","purl":"pkg:golang/github.com/kubeedge/kubeedge","ranges":["<1.9.4",">=1.10.0 <1.10.2",">=1.11.0 <1.11.1"],"fixed":["1.9.4","1.10.2","1.11.1"]}]}],"attribution":["This product uses the NVD API but is not endorsed or certified by the NVD.","EPSS scores: FIRST Exploit Prediction Scoring System, https://www.first.org/epss","Known exploited vulnerabilities: CISA Known Exploited Vulnerabilities Catalog, https://www.cisa.gov/known-exploited-vulnerabilities-catalog","Package advisories: OSV (https://osv.dev), from the GitHub Advisory Database, PyPA, Go, RustSec and other ecosystem databases, under CC-BY 4.0 or CC0","CVE records: the CVE Program's CVE List (https://www.cve.org), under its terms of use (https://www.cve.org/Legal/TermsOfUse).
