Vulnerability in Red Hat Multicluster Global Hub
CVE-2026-83550
A flaw was found in postgres-exporter. Due to the blank import of `net/http/pprof`, debug endpoints are exposed on the unauthenticated metrics listener. A remote attacker within the cluster network can access these endpoints. This allows for information disclosure, potentially revealing process arguments, full goroutine stacks, and sensitive data like database connection strings or passwords from heap dumps. Additionally, repeated CPU profiling through these endpoints can lead to a denial of service.
