{"id":"CVE-2021-20278","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.","aliases":["GHSA-ggjr-2f7v-vhq4","GO-2022-0700"],"modified":"2026-07-09T00:22:14.983606Z","published":"2021-05-28T11:15:08.077Z","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"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/kiali/kiali","events":[{"introduced":"0"},{"fixed":"1f8fdfee3a794b856c5aa0b4771db2646c109fe8"}],"database_specific":{"cpe":"cpe:2.3:a:kiali:kiali:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"1.31.0"}],"source":"CPE_RANGE"}}],"versions":["v0.10.0","v0.9.1","v0.9.0","v0.6.0","v0.5.0","v0.4.0","0.1.0.Alpha"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2021-20278.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N"}]}
