Summary

A flaw in postgres-exporter affects Red Hat Multicluster Global Hub. A blank import of net/http/pprof exposes debug endpoints on the unauthenticated metrics listener (CWE-489). A remote attacker within the cluster network can reach these endpoints to read process arguments, goroutine stacks and secrets such as database connection strings from heap dumps, and repeated CPU profiling can cause a denial of service.

Description from the CNA

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.
