{"id":"CVE-2021-20278","aliases":["GHSA-ggjr-2f7v-vhq4","GO-2022-0700"],"url":"https://o3.security/vulnerability/CVE-2021-20278","summary":"Kiali Authentication Bypass vulnerability","details":"An authentication bypass vulnerability was found in Kiali in versions before 1.31.0 when the authentication strategy `OpenID` is used. When RBAC is enabled, Kiali assumes that some of the token validation is handled by the underlying cluster. When OpenID `implicit flow` is used with RBAC turned off, this token validation doesn't occur, and this allows a malicious user to bypass the authentication.","published":"2021-05-28T11:15:08.077Z","modified":"2026-07-09T00:22:14.983606Z","cvss":{"score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"},"epss":null,"cisaKev":null,"exploitsKnown":null,"affectedPackages":[{"ecosystem":"Go","name":"github.com/kiali/kiali","fixedVersion":"1.31.0"}],"fix":null,"references":[{"type":"ADVISORY","url":"https://kiali.io/news/security-bulletins/kiali-security-002/"},{"type":"FIX","url":"https://bugzilla.redhat.com/show_bug.cgi?id=1937171"}],"provenance":{"sources":["OSV.dev","FIRST.org (EPSS)"],"lastVerified":"2026-07-09T00:22:14.983606Z"}}
