Prometheus targets API endpoint Vulnerability Scanner

Prometheus is an open-source, metrics-based event monitoring and alerting solution for cloud applications. It is used by nearly 800 cloud-native organizations including Uber, Slack, Robinhood, and more. By scraping real-time metrics from various endpoints, Prometheus allows easy observation of a system’s state in addition to observation of hardware and software metrics such as memory usage, network usage and software-specific defined metrics (ex. number of failed login attempts to a web application).

The targets endpoint exposes services belonging to the infrastructure, including their roles and labels. In addition to showing the target machine addresses, the endpoint also exposes metadata labels that are added by the target provider. These labels are intended to contain non-sensitive values, like the name of the server or its description, but various cloud platforms may automatically expose sensitive data in these labels, oftentimes without the developer's knowledge.
