## Technical details

Server-side request forgery (SSRF) in the fetch-metadata endpoint of internal/handlers/metadata_api.go allows an attacker to send requests to arbitrary URLs by manipulating the target destination parameter. The vulnerability exists because the endpoint did not properly validate request destinations before fetching metadata. An unauthenticated remote attacker can trigger server-side HTTP requests to internal or restricted resources.
