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."}],"source":{"advisory":"GHSA-8mg2-6588-r4hw","discovery":"UNKNOWN"}},"adp":[{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2026-06-05T19:40:35.029663Z","id":"CVE-2026-46389","options":[{"Exploitation":"none"},{"Automatable":"yes"},{"Technical Impact":"total"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2026-06-05T19:40:55.970Z"}}]}}
