CVE-2026-50163
A flaw was found in oras-go, a Go library used for managing OCI Open Container Initiative artifacts. An attacker can exploit this vulnerability by providing a specially crafted tarball containing a malicious hardlink. When this tarball is extracted, the hardlink can be manipulated to point to fil...
CVE-2026-48978
A flaw was found in oras-go. The auth.Client in oras-go does not properly validate the scheme or host of the realm URL provided in a registry's WWW-Authenticate: Bearer challenge. A remote attacker, operating a malicious registry or performing a man-in-the-middle attack, could exploit this to...
CVE-2026-50162
A flaw was found in oras-go. The file content store, intended to confine writes to a specified working directory, does not properly account for symbolic link symlink traversal. A remote attacker, by providing a specially crafted blob title, could exploit this vulnerability to create files outside...

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...

GHSA-JXPM-75MH-9FP7 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...

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....
