A flaw was found in OpenShift Container Platform. Completed pods with restartPolicy: Never do not count toward ResourceQuota pod limits, and Kubernetes events are not quota-scoped. A non-privileged user who can create pods in a namespace can exploit this to generate a large volume of events that accumulate in etcd, causing API server performance degradation across the cluster.
A flaw was found in the OpenShift Container Platform build system. A user with the edit ClusterRole can inject arbitrary environment variables, such as LDPRELOAD or httpproxy, into docker-build containers through the buildconfigs/instantiate API. This incomplete fix for a previous vulnerability allows for information disclosure, specifically impacting the confidentiality of build traffic.

The Tempo Operator in OpenShift Distributed Tracing creates a ServiceAccount, ClusterRole, and ClusterRoleBinding when a user deploys a TempoStack or TempoMonolithic instance. This design allows any user with full access to their namespace to retrieve the associated ServiceAccount token and utilize it to make privileged API calls to:
Validate bearer tokens using the TokenReview API.
Check user permissions using the SubjectAccessReview API.

A denial of service (DoS) vulnerability was found in OpenShift. This flaw allows attackers to exploit the GraphQL batching functionality. The vulnerability arises when multiple queries can be sent within a single request, enabling an attacker to submit a request containing thousands of aliases in one query. This issue causes excessive resource consumption, leading to application unavailability for legitimate users.
