## Overview

A flaw was found in opentelemetry-exporter-otlp-proto-http. When certificate configuration environment variables are set to empty strings, Transport Layer Security (TLS) verification is unintentionally disabled. A man-in-the-middle attacker can exploit this improper certificate validation to impersonate the telemetry collector, leading to information disclosure and alteration of exported metrics, traces, logs, and authentication headers.
