{"id":"CVE-2026-46389","state":"PUBLISHED","title":"UDS Identity Config has a client authentication bypass in `ClientIdAndKubernetesSecretAuthenticator`","description":"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.","publishedAt":"2026-06-05T18:10:47.173Z","updatedAt":"2026-06-05T19:40:55.970Z","severity":{"score":10,"label":"Critical","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["defenseunicorns uds-identity-config"],"affected":[{"vendor":"defenseunicorns","product":"uds-identity-config","versions":[{"version":">= 0.11.0, < 0.26.1","status":"affected"}]}],"references":["https://github.com/defenseunicorns/uds-identity-config/security/advisories/GHSA-8mg2-6588-r4hw","https://github.com/defenseunicorns/uds-identity-config/releases/tag/v0.26.1"],"weaknesses":["CWE-287","CWE-303"],"ingestedAt":"2026-10-29T20:12:07.131Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2026/46xxx/CVE-2026-46389.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.2","cveMetadata":{"cveId":"CVE-2026-46389","state":"PUBLISHED","datePublished":"2026-06-05T18:10:47.173Z","dateUpdated":"2026-06-05T19:40:55.970Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2026-05-13T19:53:47.922Z"},"containers":{"cna":{"title":"UDS Identity Config has a client authentication bypass in `ClientIdAndKubernetesSecretAuthenticator`","descriptions":[{"lang":"en","value":"UDS Identity Config builds the Keycloak configuration image (realm, plugins, theme, truststore, JARs) consumed by UDS Core's Identity deployment.
