CVE-2026-46389
No affected components available
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.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The vulnerability can affect other systems as well, not just the initial system. There is a high impact on the confidentiality of the information. There is a high impact on the integrity of the data. There is a high impact on the availability of the system.
Active exploitation in the wild has been confirmed. Immediate patching or mitigation is required.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
