GHSA-VH4V-2XQ2-G5CG ORAS Go forwards registry credentials across registry redirects

ORAS Go forwards registry credentials across registry redirects Reporter / public credit: JUNYI LIU Summary ORAS Go can forward registry credentials configured for one registry origin to a different HTTP origin during registry redirects. There are two related paths: 1. A manifest or metadata...

Symlink Attack

Overview Affected versions of this package are vulnerable to Symlink Attack through improper validation of hardlink targets during tar extraction. An attacker can access or modify files outside the intended extraction directory by crafting a malicious tarball with a hardlink entry whose target is...

GHSA-FXHP-MV3V-67QP `oras-go` tar extraction: Hardlink entry with relative Linkname escapes extract dir via process CWD resolution

Root cause The tar-extraction helper ensureLinkPath at content/file/utils.go:262-275 validates that a hardlink's target resolves inside the extract base, but then returns the original unresolved target string back to the caller: go func ensureLinkPathbaseAbs, baseRel, link, target string string,...

GHSA-8XWF-RJM4-XVHV oras-go has file store write outside workingDir via symlink traversal

The file content store in oras-go attempts to confine writes to workingDir when AllowPathTraversalOnWrite=false, but the guard is lexical and does not account for symlink traversal. If workingDir contains a symlink path component and an attacker-controlled blob title via ocispec.AnnotationTitle...

oras-go blob upload vulnerable to credential forwarding via unvalidated Location header

Summary oras-go follows a registry-controlled Location header during the monolithic blob upload flow and reuses the Authorization header from the initial POST request for the subsequent PUT request. If a malicious registry returns a cross-host Location, oras-go can send the caller's credentials t...

Server-side Request Forgery (SSRF)

Overview Affected versions of this package are vulnerable to Server-side Request Forgery SSRF via the blobStore.completePushAfterInitialPost process. An attacker can obtain sensitive credentials by manipulating the Location header to redirect requests to an attacker-controlled endpoint, causing t...

GHSA-XF85-363P-868W oras-go: Malicious registry can hijack Bearer token realm to exfiltrate credentials and refresh tokens

Summary oras-go's auth.Client follows the realm URL from a registry's WWW-Authenticate: Bearer challenge without validating its scheme or host. The realm field is server-controlled by design in the OCI/distribution spec — registries legitimately point token requests at a separate auth endpoint e....
