{"cve":"CVE-2022-31078","nvd":{"published":"2022-07-11T21:15:08.267","modified":"2026-06-17T04:44:44.967","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, the CloudCore Router does not impose a limit on the size of responses to requests made by the REST handler. An attacker could use this weakness to make a request that will return an HTTP response with a large body and cause DoS of CloudCore. In the HTTP Handler API, the rest handler makes a request to a pre-specified handle. The handle will return an HTTP response that is then read into memory. The consequence of the exhaustion is that CloudCore will be in a denial of service. Only an authenticated user of the cloud can make an attack. It will be affected only when users enable `router` module in the config file `cloudcore.yaml`. This bug has been fixed in Kubeedge 1.11.1, 1.10.2, and 1.9.4. As a workaround, disable the router switch in the config file `cloudcore.yaml`.","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-qpx3-9565-5xwm","https://github.com/kubeedge/kubeedge/security/advisories/GHSA-qpx3-9565-5xwm"],"products":["linuxfoundation:kubeedge"],"source":"nvd","synced_at":"2026-10-19T21:33:44.859608815+00:00"},"epss":{"cve":"CVE-2022-31078","score":0.00703,"percentile":0.53295,"date":"2026-11-01"},"kev":null,"osv":[{"id":"GHSA-qpx3-9565-5xwm","url":"https://osv.dev/vulnerability/GHSA-qpx3-9565-5xwm","summary":"KubeEdge CloudCore Router memory exhaustion vulnerability","modified":"2024-08-21T15:26:46.659005Z","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-2022-0510","url":"https://osv.dev/vulnerability/GO-2022-0510","summary":"KubeEdge CloudCore Router memory exhaustion vulnerability in github.com/kubeedge/kubeedge","modified":"2026-03-03T04:50:27.649049Z","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).
