{"id":"CVE-2026-46389","summary":"UDS Identity Config has a client authentication bypass in `ClientIdAndKubernetesSecretAuthenticator`","details":"UDS Identity Config builds the Keycloak configuration image (realm, plugins, theme, truststore, JARs) consumed by UDS Core's Identity deployment. In versions 0.11.0 through 0.26.0, a logic error in the `client-kubernetes-secret` Keycloak client authenticator (shipped by `uds-identity-config` and consumed by UDS Core) causes the submitted `client_secret` to be overwritten with the mounted Kubernetes secret before comparison. An attacker who can reach the Keycloak token endpoint and knows a `client_id` using this authenticator can authenticate as that client with any `client_secret` value and obtain OAuth2 tokens scoped to the client's service account. In the case of the `uds-operator` client this token can be used to registry/modify other clients. Version 0.26.1 patches the issue.","aliases":["GHSA-8mg2-6588-r4hw"],"modified":"2026-07-08T08:14:00.620697590Z","published":"2026-06-05T18:10:47.173Z","database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46389.json","cna_assigner":"GitHub_M","cwe_ids":["CWE-287","CWE-303"]},"references":[{"type":"WEB","url":"https://github.com/defenseunicorns/uds-identity-config/releases/tag/v0.26.1"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/46xxx/CVE-2026-46389.json"},{"type":"ADVISORY","url":"https://github.com/defenseunicorns/uds-identity-config/security/advisories/GHSA-8mg2-6588-r4hw"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-46389"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/defenseunicorns/uds-identity-config","events":[{"introduced":"e30c0062dcd9de0727fe59c37af9c6dde0d4f719"},{"fixed":"596b28d40f7a78b6f8b03c872ac79ba7a3ab2fb0"}],"database_specific":{"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"],"extracted_events":[{"introduced":"0.11.0"},{"fixed":"0.26.1"}],"cpe":"cpe:2.3:a:defenseunicorns:uds_identity_config:*:*:*:*:*:*:*:*"}}],"versions":["v0.26.0","v0.25.0","v0.24.0","v0.23.0","v0.22.1","v0.22.0","v0.21.0","v0.20.0","v0.19.1","v0.19.0","v0.18.0","v0.17.0","v0.16.3","v0.16.2","v0.16.1","v0.16.0","v0.15.2","v0.15.1","v0.15.0","v0.14.1","v0.14.0","v0.13.1","v0.13.0","v0.12.1","v0.12.0","v0.11.1","v0.11.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2026-46389.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H"}]}
