In affected versions Envoy transitions a H/2 connection to the CLOSED state when it receives a GOAWAY frame without any streams outstanding. The connection state is transitioned to DRAINING when it receives a SETTING frame with the SETTINGS_MAX_CONCURRENT_STREAMS parameter set to 0. Receiving these two frames in the same I/O event results in abnormal termination of the Envoy process due to invalid state transition from CLOSED to DRAINING. A sequence of H/2 frames delivered by an untrusted upstream server will result in Denial of Service in the presence of untrusted **upstream** servers. Envoy versions 1.19.1, 1.18.4 contain fixes to stop processing of pending H/2 frames after connection transition to the CLOSED state.\n\n\ud83d\udcd6 Read\n\nvia \"National Vulnerability Database\".", "url": "https://t.me/cibsecurity/27849"}, {"timestamp": "2022-06-15T15:48:00Z", "date_only": false, "value": "2022-06-15T15:48Z", "kind": "other", "label": "Last Modified Date", "source": "gsd \u00b7 GSD-2021-32780", "record": "GSD-2021-32780", "field": "namespaces.nvd.nist.gov.lastModifiedDate"}, {"timestamp": "2023-12-13T01:23:08.764Z", "date_only": false, "value": "2023-12-13T01:23:08.764715Z", "kind": "other", "label": "Updated", "source": "gsd \u00b7 GSD-2021-32780", "record": "GSD-2021-32780", "field": "gsd.osvSchema.modified"}, {"timestamp": "2024-03-06T10:57:54.997Z", "date_only": false, "value": "2024-03-06T10:57:54.997Z", "kind": "milestone", "label": "Published", "source": "bitnami_vulndb \u00b7 BIT-ENVOY-2021-32780", "record": "BIT-ENVOY-2021-32780", "field": "published"}, {"timestamp": "2024-08-03T23:33:56.068Z", "date_only": false, "value": "2024-08-03T23:33:56.068Z", "kind": "other", "label": "Updated", "source": "cvelistv5", "record": "cve-2021-32780", "field": "cveMetadata.dateUpdated"}, {"timestamp": "2024-08-03T23:33:56.068Z", "date_only": false, "value": "2024-08-03T23:33:56.068Z", "kind": "other", "label": "Updated", "source": "cvelistv5 / CVE", "record": "cve-2021-32780", "field": "containers.adp.0.providerMetadata.dateUpdated"}, {"timestamp": "2026-06-17T03:53:36.990Z", "date_only": false, "value": "2026-06-17T03:53:36.990", "kind": "other", "label": "Updated", "source": "fkie_nvd \u00b7 FKIE_CVE-2021-32780", "record": "FKIE_CVE-2021-32780", "field": "lastModified"}, {"timestamp": "2026-09-08T08:34:36.952Z", "date_only": false, "value": "2026-09-08T08:34:36.952Z", "kind": "other", "label": "Updated", "source": "bitnami_vulndb \u00b7 BIT-ENVOY-2021-32780", "record": "BIT-ENVOY-2021-32780", "field": "modified"}]}
