Vulnerability from github – Published: 2026-01-22 20:28 – Updated: 2026-02-27 21:37Summary
The legacy TUF client pkg/tuf/client.go, which supports caching target files to disk, constructs a filesystem path by joining a cache base directory with a target name sourced from signed target metadata, but it does not validate that the resulting path stays within the cache base directory.
Note that this should only affect clients that are directly using the TUF client in sigstore/sigstore or are using an older version of Cosign. As this TUF client implementation is deprecated, users should migrate to https://github.com/sigstore/sigstore-go/tree/main/pkg/tuf as soon as possible.
Note that this does not affect users of the public Sigstore deployment, where TUF metadata is validated by a quorum of trusted collaborators.
Impact
A malicious TUF repository can trigger arbitrary file overwriting, limited to the permissions that the calling process has.
Workarounds
Users can disable disk caching for the legacy client by setting SIGSTORE_NO_CACHE=true in the environment, migrate to https://github.com/sigstore/sigstore-go/tree/main/pkg/tuf, or upgrade to the latest sigstore/sigstore release.

Vulnerability from github – Published: 2026-01-21 16:19 – Updated: 2026-01-22 15:43Security Disclosure: Improper validation of configured threshold for delegations
Summary
A compromised or misconfigured TUF repository can have the configured value of signature thresholds set to 0, which effectively disables signature verification.
Impact
Unathorized modification to TUF metadata files is possible at rest, or during transit as no integrity checks are made.
Patches
Upgrade to v2.3.1
Workarounds
Always make sure that the TUF metadata roles are configured with a threshold of at least 1.
Affected code:
The metadata.VerifyDelegate did not verify the configured threshold prior to comparison. This means that a misconfigured TUF repository could disable the signature verification by setting the threshold to 0, or a negative value (and so always make the signature threshold computation to pass).

GHSA-JQC5-W2XX-5VQ4
Vulnerability from github – Published: 2026-01-26 23:49 – Updated: 2026-01-29 03:26Security Vulnerability: Path Traversal in TAP 4 Multirepo Client
Summary
go-tuf's TAP 4 Multirepo Client uses the map file repository name string (repoName) as a filesystem path component when selecting the local metadata cache directory. If an application accepts a map file from an untrusted source, an attacker can supply a repoName containing traversal (e.g., ../escaped-repo) and cause go-tuf to create directories and write the root metadata file outside the intended LocalMetadataDir cache base, within the running process's filesystem permissions.
Affected Component
| Field | Value |
|---|---|
| File | metadata/multirepo/multirepo.go |
| Function | (*MultiRepoClient) initTUFClients() error |
| Callsite | metadataDir := filepath.Join(client.Config.LocalMetadataDir, repoName) (around line 129 at the pinned commit) |
Impact
When the TAP 4 map file content is attacker-controlled, this enables arbitrary file write relative to the process permissions (via metadata persistence during client initialization). This can be used to overwrite files writable by the process (for example, configuration files in writable directories) and may enable further compromise depending on the deployment environment.
Note: Exploitability is deployment-dependent. If the map file is always local and trusted (not attacker-controlled), this reduces to a misconfiguration risk rather than a remotely triggerable issue.
Attacker Model
- Attacker can cause the application to load a TAP 4 map file whose
repositorieskeys are attacker-controlled (for example: fetched from a URL, supply-chain substituted, or otherwise attacker-influenced input). - Local caching is enabled (
DisableLocalCache=false) and the configuredLocalMetadataDiris writable by the running process.
Claim Ceiling: HIGH when the map file is attacker-controlled; if the map file is always local and trusted, this is closer to a configuration footgun and likely lands as MEDIUM/LOW.
| Field | Value |
|---|---|
| Affected Versions | ≤ 2.4.0 |
| Verified On | Commit bde5f18dc95dfac365fc452ee4e278e5fd66d4b4 (tag v2.4.0) |
Note: First affected version has not been bisected.
Reproduction
Attachments include poc.zip with:
- canonical.log (contains [CALLSITE_HIT], [PROOF_MARKER])
- control.log (contains [CALLSITE_HIT], [NC_MARKER], does not contain [PROOF_MARKER])
- fix.patch (minimal validation sketch)
Expected: Multirepo repository names are treated as identifiers; a TAP 4 map file containing traversal or absolute paths is rejected (or safely normalized so that all writes stay under LocalMetadataDir).
Actual: A traversal repoName escapes LocalMetadataDir and go-tuf persists root.json under the escaped path during initialization.
Run Local Repro
rm -rf _poc
mkdir -p _poc
unzip -q -o poc.zip -d _poc
cd _poc/poc
make canonical
make control
Workarounds
- Treat TAP 4 map files as trusted configuration only (do not fetch from untrusted sources).
- Validate repo names before passing the map file to go-tuf (reject absolute paths, path separators, and traversal components like
./..). - If acceptable for the application, disable local caching to avoid writing metadata to disk (
DisableLocalCache=true).
Suggested Remediation
Validate multirepo repository names as identifiers (not paths) before using them in filepath.Join. Reject:
- Absolute paths
- Path separators (/ and \)
- Traversal components (. and ..)
If it is important to accept a wider set of repo names, a safer alternative is to map repo names to a stable, validated directory name (for example via encoding or hashing) and to ensure all writes stay under the cache base directory.
Triage Questions
- Is the TAP 4 map file expected to ever be fetched from untrusted sources in supported deployments?
- Should invalid repo names be treated as a hard error (reject initialization), or as a soft error (skip that repository entry)?

If the map file is always local and trusted (not attacker-controlled), this reduces to a misconfiguration risk rather than a remotely triggerable issue.\n\n## Attacker Model\n\n- Attacker can cause the application to load a TAP 4 map file whose `repositories` keys are attacker-controlled (for example: fetched from a URL, supply-chain substituted, or otherwise attacker-influenced input).\n- Local caching is enabled (`DisableLocalCache=false`) and the configured `LocalMetadataDir` is writable by the running process.\n\n**Claim Ceiling:** HIGH when the map file is attacker-controlled; if the map file is always local and trusted, this is closer to a configuration footgun and likely lands as MEDIUM/LOW.\n\n| Field | Value |\n|-------|-------|\n| **Affected Versions** | \u2264 2.4.0 |\n| **Verified On** | Commit `bde5f18dc95dfac365fc452ee4e278e5fd66d4b4` (tag v2.4.0) |\n\n\u003e **Note:** First affected version has not been bisected.\n\n## Reproduction\n\nAttachments include `poc.zip` with:\n- `canonical.log` (contains `[CALLSITE_HIT]`, `[PROOF_MARKER]`)\n- `control.log` (contains `[CALLSITE_HIT]`, `[NC_MARKER]`, does not contain `[PROOF_MARKER]`)\n- `fix.patch` (minimal validation sketch)\n\n**Expected:** Multirepo repository names are treated as identifiers; a TAP 4 map file containing traversal or absolute paths is rejected (or safely normalized so that all writes stay under `LocalMetadataDir`).\n\n**Actual:** A traversal `repoName` escapes `LocalMetadataDir` and go-tuf persists `root.json` under the escaped path during initialization.\n\n### Run Local Repro\n\n```bash\nrm -rf _poc\nmkdir -p _poc\nunzip -q -o poc.zip -d _poc\ncd _poc/poc\nmake canonical\nmake control\n```\n\n## Workarounds\n\n1. Treat TAP 4 map files as trusted configuration only (do not fetch from untrusted sources).\n2. Validate repo names before passing the map file to go-tuf (reject absolute paths, path separators, and traversal components like `.` / `..`).\n3. If acceptable for the application, disable local caching to avoid writing metadata to disk (`DisableLocalCache=true`).\n\n## Suggested Remediation\n\nValidate multirepo repository names as identifiers (not paths) before using them in `filepath.Join`. Reject:\n- Absolute paths\n- Path separators (`/` and `\\`)\n- Traversal components (`.` and `..`)\n\nIf it is important to accept a wider set of repo names, a safer alternative is to map repo names to a stable, validated directory name (for example via encoding or hashing) and to ensure all writes stay under the cache base directory.\n\n## Triage Questions\n\n1. Is the TAP 4 map file expected to ever be fetched from untrusted sources in supported deployments?\n2. Should invalid repo names be treated as a hard error (reject initialization), or as a soft error (skip that repository entry)?\n\n## Attachments\n\n- [poc.zip](https://github.com/user-attachments/files/24849854/poc.zip)\n- [addendum.md](https://github.com/user-attachments/files/24849855/addendum.md)\n- [e2e.zip](https://github.com/user-attachments/files/24849856/e2e.zip)\n- [PR_DESCRIPTION.md](https://github.com/user-attachments/files/24849858/PR_DESCRIPTION.md)\n\n---\n\n*Reported by: Oleh*",

Vulnerability from github – Published: 2025-03-21 22:04 – Updated: 2025-04-10 13:02Summary
Function parse.ParseUnverified currently splits (via a call to strings.Split) its argument (which is untrusted data) on periods.
As a result, in the face of a malicious request whose Authorization header consists of Bearer followed by many period characters, a call to that function incurs allocations to the tune of O(n) bytes (where n stands for the length of the function's argument), with a constant factor of about 16. Relevant weakness: CWE-405: Asymmetric Resource Consumption (Amplification)

GHSA-MQQF-5WVP-8FH8
Vulnerability from github – Published: 2026-01-14 21:18 – Updated: 2026-06-18 13:02Summary
The RedirectSlashes function in middleware/strip.go does not perform correct input validation and can lead to an open redirect vulnerability.
Details
The RedirectSlashes function performs a Trim to all forward slash (/) characters, while prepending a single one at the begining of the path (Line 52).
However, it does not trim backslashes (\).
File: middleware/strip.go
41: func RedirectSlashes(next http.Handler) http.Handler {
...
51: // Trim all leading and trailing slashes (e.g., "//evil.com", "/some/path//")
52: path = "/" + strings.Trim(path, "/")
...
62: }
Also, from version 5.2.2 onwards the RedirectSlashes function does not take into consideration the Host Header in the redirect response returned. This was done in order to combat another [vulnerability](https://github.com/go-chi/chi/security/advisories/GHSA-vrw8-fxc6-2r93).
The above make it possible for a response in the following form:
HTTP/1.1 301 Moved Permanently
Location: /\evil.com
The /\evil.com will be transformed by most browsers (Chrome, Firefox, etc. not Safari) into //evil.com which is a protocol relative URL and will result in a redirect to evil.com, essentially making it an open redirect vulnerability.
PoC
A minimal working example can be seen below.
package main
import (
"fmt"
"net/http"
"github.com/go-chi/chi/v5"
"github.com/go-chi/chi/v5/middleware"
)
func main() {
r := chi.NewRouter()
r.Use(middleware.RedirectSlashes)
r.Get("/*", func(w http.ResponseWriter, r *http.Request) {
w.WriteHeader(http.StatusOK)
})
fmt.Println("Server starting on port 8081...")
if err := http.ListenAndServe(":8081", r); err != nil {
fmt.Printf("Error starting server: %v\n", err)
}
}
And when we request the path /\evil.com (needs a second backslash or URL encoding in the terminal), the HTTP Redirect Location is just /\evil.com without any domain/Host information.
$ curl -I localhost:8081/\\evil.com/
HTTP/1.1 301 Moved Permanently
Content-Type: text/html; charset=utf-8
Location: /\evil.com
$ curl -I localhost:8081/%5Cevil.com/
HTTP/1.1 301 Moved Permanently
Content-Type: text/html; charset=utf-8
Location: /\evil.com
This opened in a browser (Chrome, Firefox) will result in a transformation to //evil.com which in turn will result in a redirect to evil.com.
Impact
This essentially consists of an open redirect vulnerability, provided that victim users use the most popular browsers (Chrome, Firefox, etc. It does not work in e.g. Safari).
The attacker can construct a malicious URL on a domain of a legitimate website and send it to the victim user. The victim users thinking that they will click on a legitimate website's URL, they will unknowingly be reidrected to an attacker controlled website.
This can lead to credential theft if the victim gets redirected to a phishing website, to malware that is hosted on the attacker controlled website etc. Also, it has a greate reputation / business impact for the affected legitimate website.
In order to exploit this vulnerability the attacker does not need to be authenticated or have ay other priviledge / knowledge regarding the affected application.

Vulnerability from github – Published: 2026-03-05 00:10 – Updated: 2026-03-31 14:21This issue affects Docker CLI through 29.1.5
Impact
Docker CLI for Windows searches for plugin binaries in C:\ProgramData\Docker\cli-plugins, a directory that does not exist by default. A low-privileged attacker can create this directory and place malicious CLI plugin binaries (docker-compose.exe, docker-buildx.exe, etc.) that are executed when a victim user opens Docker Desktop or invokes Docker CLI plugin features, and allow privilege-escalation if the docker CLI is executed as a privileged user.
This issue affects Docker CLI through v29.1.5 (fixed in v29.2.0). It impacts Windows binaries acting as a CLI plugin manager via the github.com/docker/cli/cli-plugins/manager package, which is consumed by downstream projects such as Docker Compose.
Docker Compose became affected starting in v2.31.0, when it incorporated the relevant CLI plugin manager code (see https://github.com/docker/compose/pull/12300), and is fixed in v5.1.0.
This issue does not impact non-Windows binaries or projects that do not use the plugin manager code.
Patches
Fixed version starts with 29.2.0
This issue was fixed in https://github.com/docker/cli/commit/13759330b1f7e7cb0d67047ea42c5482548ba7fa (https://github.com/docker/cli/pull/6713), which removed %PROGRAMDATA%\Docker\cli-plugins from the list of paths used for plugin-discovery on Windows.
Workarounds
None

Vulnerability from github – Published: 2026-03-18 20:10 – Updated: 2026-03-25 18:12Impact
What kind of vulnerability is it? Who is impacted?
It is an Authorization Bypass resulting from Improper Input Validation of the HTTP/2 :path pseudo-header.
The gRPC-Go server was too lenient in its routing logic, accepting requests where the :path omitted the mandatory leading slash (e.g., Service/Method instead of /Service/Method). While the server successfully routed these requests to the correct handler, authorization interceptors (including the official grpc/authz package) evaluated the raw, non-canonical path string. Consequently, "deny" rules defined using canonical paths (starting with /) failed to match the incoming request, allowing it to bypass the policy if a fallback "allow" rule was present.
Who is impacted?
This affects gRPC-Go servers that meet both of the following criteria:
1. They use path-based authorization interceptors, such as the official RBAC implementation in google.golang.org/grpc/authz or custom interceptors relying on info.FullMethod or grpc.Method(ctx).
2. Their security policy contains specific "deny" rules for canonical paths but allows other requests by default (a fallback "allow" rule).
The vulnerability is exploitable by an attacker who can send raw HTTP/2 frames with malformed :path headers directly to the gRPC server.
Patches
Has the problem been patched? What versions should users upgrade to?
Yes, the issue has been patched. The fix ensures that any request with a :path that does not start with a leading slash is immediately rejected with a codes.Unimplemented error, preventing it from reaching authorization interceptors or handlers with a non-canonical path string.
Users should upgrade to the following versions (or newer): * v1.79.3 * The latest master branch.
It is recommended that all users employing path-based authorization (especially grpc/authz) upgrade as soon as the patch is available in a tagged release.
Workarounds
Is there a way for users to fix or remediate the vulnerability without upgrading?
While upgrading is the most secure and recommended path, users can mitigate the vulnerability using one of the following methods:
1. Use a Validating Interceptor (Recommended Mitigation)
Add an "outermost" interceptor to your server that validates the path before any other authorization logic runs:
func pathValidationInterceptor(ctx context.Context, req any, info *grpc.UnaryServerInfo, handler grpc.UnaryHandler) (any, error) {
if info.FullMethod == "" || info.FullMethod[0] != '/' {
return nil, status.Errorf(codes.Unimplemented, "malformed method name")
}
return handler(ctx, req)
}
// Ensure this is the FIRST interceptor in your chain
s := grpc.NewServer(
grpc.ChainUnaryInterceptor(pathValidationInterceptor, authzInterceptor),
)
2. Infrastructure-Level Normalization
If your gRPC server is behind a reverse proxy or load balancer (such as Envoy, NGINX, or an L7 Cloud Load Balancer), ensure it is configured to enforce strict HTTP/2 compliance for pseudo-headers and reject or normalize requests where the :path header does not start with a leading slash.
3. Policy Hardening
Switch to a "default deny" posture in your authorization policies (explicitly listing all allowed paths and denying everything else) to reduce the risk of bypasses via malformed inputs.
