CVE-2026-50151

Linuxfoundation Oras server-side request forgery (SSRF)

7.5 HIGHPublic exploitEPSS 0.38%
  1. Published17 Jul 2026

Description

oras-go is a Go library for managing OCI artifacts. Prior to 2.6.1, registry/remote/repository.go in blobStore.completePushAfterInitialPost follows a registry-controlled Location header during monolithic blob upload and reuses the Authorization header from the initial POST request for the subsequent PUT request, allowing a malicious registry to return a cross-host Location and receive the caller's credentials at an attacker-controlled endpoint. This issue is fixed in version 2.6.1.
