CVE-2023-49799Public exploitNetwork attack vector

Credential disclosure via whitespace-prefixed proxy URLs

Published Dec 8, 2023 · Updated Nov 27, 2024

SSRF in Johann Schopplich Nuxt API Party before 0.22.1 allows remote attackers to leak API credentials via a crafted proxy path. The server handler rejects absolute paths only when they match ^https?:// at the first character, while Fetch trims leading HTTP whitespace before resolving and requesting the URL. An unauthenticated request to the generated proxy route can therefore make the server contact an attacker-chosen host and forward configured endpoint credentials.
