This unintended inclusion exposes Go debug endpoints on the default metrics listener port without requiring authentication. Any attacker with network access to the postgres-exporter instance - typically within a Kubernetes pod network or cluster environment - can query these endpoints to retrieve sensitive runtime data.\u003c/p\u003e\n\u003cp\u003eThe exposed information includes process arguments, full goroutine stacks, and memory content, which may contain hardcoded database connection strings, credentials, or sensitive application data extracted via heap dumps. Furthermore, an attacker can intentionally initiate CPU profiling tasks, leading to resource exhaustion and denial of service. The impact is significant for environments where internal cluster traffic is not strictly partitioned or where the metrics port is exposed to wider network segments.\u003c/p\u003e\n\u003ch2 id=\"impact\"\u003eImpact\u003c/h2\u003e\n\u003cp\u003eSuccessful exploitation leads to unauthorized information disclosure, potentially resulting in the compromise of database credentials or internal system configuration details.
