Or a logging system double-encoded an error message. The correct approach is to URL-encode the base URL of the metadata server. Only query parameters (if any) should be encoded. Developers typically use these fetches when they need

Developers typically use these fetches when they need to authenticate with other Google APIs (like Cloud Storage or BigQuery) without hardcoding secret keys. Using curl (Linux/VM): import time import requests # Using Application Default

While powerful, this endpoint is a high-value target for attackers: View and query VM metadata | Compute Engine

An attacker interacting with an SSRF vulnerability will typically target the following final paths to extract a live authorization token:
