## Overview

Flame through 2.4.0 contains an information exposure vulnerability in the unauthenticated GET /api/config endpoint that returns the entire configuration object without field redaction. Attackers can retrieve the stored weather API key and internal operational settings by sending a single unauthenticated request to consume provider quota or access sensitive configuration data.
