{"id":"CVE-2020-8660","details":"CNCF Envoy through 1.13.0 TLS inspector bypass. TLS inspector could have been bypassed (not recognized as a TLS client) by a client using only TLS 1.3. Because TLS extensions (SNI, ALPN) were not inspected, those connections might have been matched to a wrong filter chain, possibly bypassing some security restrictions in the process.","aliases":["BIT-envoy-2020-8660","GHSA-c4g8-7grc-5wvx"],"modified":"2026-08-07T15:14:56.318418Z","published":"2020-03-04T22:15:11.343Z","references":[{"type":"ADVISORY","url":"https://access.redhat.com/errata/RHSA-2020:0734"},{"type":"ADVISORY","url":"https://github.com/envoyproxy/envoy/security/advisories/GHSA-c4g8-7grc-5wvx"},{"type":"ADVISORY","url":"https://www.envoyproxy.io/docs/envoy/v1.13.1/intro/version_history"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/envoyproxy/envoy","events":[{"introduced":"0"},{"fixed":"b5144d4e603866dfc470ab23867598fded2fed9c"},{"introduced":"bb7ceff4c3c5bd4555dff28b6e56d27f2f8be0a7"},{"fixed":"b67c14052c49890a7e3afe614d50979c346c024b"}],"database_specific":{"cpe":"cpe:2.3:a:envoyproxy:envoy:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.12.3"},{"introduced":"1.13.0"},{"fixed":"1.13.1"}],"source":"CPE_RANGE"}}],"versions":["v1.12.2","v1.13.0","v1.12.1","v1.12.0","v1.11.0","v1.10.0","v1.9.0","v1.8.0","v1.7.0","v1.6.0","v1.5.0","v1.4.0","v1.3.0","v1.2.0","v1.1.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2020-8660.json"}}],"schema_version":"1.8.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N"}]}
