What is CVE-2025-2786?

A security flaw exists in the Tempo Operator, where the creation of ServiceAccount, ClusterRole, and ClusterRoleBinding upon deploying a TempoStack or TempoMonolithic can lead to information disclosure. A user with comprehensive access to their namespace can extract ServiceAccount tokens and submit TokenReview and SubjectAccessReview requests. This action may inadvertently unveil sensitive details regarding other users' permissions within the environment. Although this vulnerability does not allow for privilege escalation or user impersonation, it presents a vector for collecting critical information that could be exploited in future attacks.
