What is CVE-2026-83550?
CVE-2026-83550 is a high-severity vulnerability in Red Hat Multicluster Global Hub, published on 6 Oct 2026. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
Weakness: CWE-489
