Process-data disclosure via exposed pprof endpoints
Published Oct 6, 2026 · Updated Oct 6, 2026
Information disclosure in Red Hat Multicluster Global Hub's postgres-exporter allows remote attackers to read process data through its metrics listener. A blank net/http/pprof import registers debug handlers on the listener without authentication, exposing process arguments, goroutine stacks, and potentially database credentials in heap dumps. Access requires reachability within the cluster network; repeated CPU profiling requests can also interrupt the exporter.
