Vulnerability Report
Generated by CyberWatcher
Description
A flaw was found in etcd, a distributed key-value store. Unauthorized users can bypass authentication or authorization checks when the gRPC API is exposed to untrusted clients. This allows them to access sensitive cluster topology information, disrupt operations through alarms, interfere with lease management, and trigger data compaction, leading to permanent data loss and disruption of critical workflows. This vulnerability can result in information disclosure and denial of service.
