CVE-2026-50151 - Vulnerability Details - OpenCVE

A flaw was found in oras-go. During the monolithic blob upload process, oras-go reuses the Authorization header for subsequent requests, even if a malicious registry provides a cross-host Location header. This vulnerability allows an attacker-controlled endpoint to receive the caller's credentials, leading to information disclosure. Additionally, it can enable client-side Server-Side Request Forgery (SSRF) to a cross-host target.
