CVE-2026-46389 (GCVE-0-2026-46389)

Vulnerability from cvelistv5 – Published: 2026-06-05 18:10 – Updated: 2026-06-05 19:40

Title
UDS Identity Config has a client authentication bypass in `ClientIdAndKubernetesSecretAuthenticator`
Summary
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.

CVE-2026-23634 (GCVE-0-2026-23634)

Vulnerability from cvelistv5 – Published: 2026-01-16 19:14 – Updated: 2026-01-16 21:38

Title
Pepr Overly Permissive RBAC ClusterRole in Admin Mode
Summary
Pepr is a type safe K8s middleware. Prior to 1.0.5 , Pepr defaults to a cluster-admin RBAC configuration and does not explicitly force or enforce least-privilege guidance for module authors. The default behavior exists to make the “getting started” experience smooth: new users can experiment with Pepr and create resources dynamically without needing to pre-configure RBAC. This vulnerability is fixed in 1.0.5.
