Vulnerability from github – Published: 2025-08-21 14:37 – Updated: 2026-01-27 21:01

Summary

go-viper's mapstructure May Leak Sensitive Information in Logs When Processing Malformed Data

Details

Summary

Use of this library in a security-critical context may result in leaking sensitive information, if used to process sensitive fields.

Details

OpenBao (and presumably HashiCorp Vault) have surfaced error messages from mapstructure as follows:

https://github.com/openbao/openbao/blob/98c3a59c040efca724353ca46ca79bd5cdbab920/sdk/framework/field_data.go#L43-L50

            _, _, err := d.getPrimitive(field, schema)
            if err != nil {
                return fmt.Errorf("error converting input for field %q: %w", field, err)
            }

where this calls mapstructure.WeakDecode(...): https://github.com/openbao/openbao/blob/98c3a59c040efca724353ca46ca79bd5cdbab920/sdk/framework/field_data.go#L181-L193


func (d *FieldData) getPrimitive(k string, schema *FieldSchema) (interface{}, bool, error) {
    raw, ok := d.Raw[k]
    if !ok {
        return nil, false, nil
    }

    switch t := schema.Type; t {
    case TypeBool:
        var result bool
        if err := mapstructure.WeakDecode(raw, &result); err != nil {
            return nil, false, err
        }
        return result, true, nil

Notably, WeakDecode(...) eventually calls one of the decode helpers, which surfaces the original value via strconv helpers:

https://github.com/go-viper/mapstructure/blob/8c61ec1924fcfa522f9fc6b4618c672db61d1a38/mapstructure.go#L720-L727

https://github.com/go-viper/mapstructure/blob/8c61ec1924fcfa522f9fc6b4618c672db61d1a38/mapstructure.go#L791-L798

https://github.com/go-viper/mapstructure/blob/8c61ec1924fcfa522f9fc6b4618c672db61d1a38/decode_hooks.go#L180

& more. These are different code paths than are fixed in the previous iteration at https://github.com/go-viper/mapstructure/security/advisories/GHSA-fv92-fjc5-jj9h.

PoC

To reproduce with OpenBao:

$ podman run --pull=always -p 8300:8300 openbao/openbao:latest server -dev -dev-root-token-id=root -dev-listen-address=0.0.0.0:8300

and in a new tab:

$ BAO_TOKEN=root BAO_ADDR=http://localhost:8300 bao auth enable userpass
Success! Enabled userpass auth method at: userpass/
$ curl -X PUT -H "X-Vault-Request: true" -H "X-Vault-Token: root" -d '{"ttl":"asdf"}' "http://localhost:8200/v1/auth/userpass/users/asdf"

--> server logs:

2025-06-25T21:32:25.101-0500 [ERROR] core: failed to run existence check: error="error converting input for field \"ttl\": time: invalid duration \"asdf\""

Impact

This is an information disclosure bug with little mitigation. See https://discuss.hashicorp.com/t/hcsec-2025-09-vault-may-expose-sensitive-information-in-error-logs-when-processing-malformed-data-with-the-kv-v2-plugin/74717 for a previous version. That version was fixed, but this is in the second part of that error message (starting at '' expected a map, got 'string' -- when the field type is string and a map is provided, we see the above information leak -- the previous example had a map type field with a string value provided).

This was rated 4.5 Medium by HashiCorp in the past iteration.

Severity ?

5.3 (Medium)

Vulnerability from github – Published: 2025-06-10 21:18 – Updated: 2025-10-23 17:36

Summary

CIRCL-Fourq: Missing and wrong validation can lead to incorrect results

Details

Impact

The CIRCL implementation of FourQ fails to validate user-supplied low-order points during Diffie-Hellman key exchange, potentially allowing attackers to force the identity point and compromise session security.

Moreover, there is an incorrect point validation in ScalarMult can lead to incorrect results in the isEqual function and if a point is on the curve.

Patches

Version 1.6.1 (https://github.com/cloudflare/circl/tree/v1.6.1) mitigates the identified issues.

We acknowledge Alon Livne (Botanica Software Labs) for the reported findings.

Severity ?

3.7 (Low)

GHSA-9H8M-3FM2-QJRQ

Vulnerability from github – Published: 2026-02-02 20:07 – Updated: 2026-02-27 21:39

Summary

OpenTelemetry Go SDK Vulnerable to Arbitrary Code Execution via PATH Hijacking

Details

Impact

The OpenTelemetry Go SDK in version v1.20.0-1.39.0 is vulnerable to Path Hijacking (Untrusted Search Paths) on macOS/Darwin systems. The resource detection code in sdk/resource/host_id.go executes the ioreg system command using a search path. An attacker with the ability to locally modify the PATH environment variable can achieve Arbitrary Code Execution (ACE) within the context of the application.

Patches

This has been patched in d45961b, which was released with v1.40.0.

GHSA-37CX-329C-33X3

Vulnerability from github – Published: 2026-02-10 00:28 – Updated: 2026-02-10 02:57

Summary

go-git improperly verifies data integrity values for .idx and .pack files

Details

Impact

A vulnerability was discovered in go-git whereby data integrity values for .pack and .idx files were not properly verified. This resulted in go-git potentially consuming corrupted files, which would likely result in unexpected errors such as object not found.

For context, clients fetch packfiles from upstream Git servers. Those files contain a checksum of their contents, so that clients can perform integrity checks before consuming it. The pack indexes (.idx) are generated locally by go-git, or the git cli, when new .pack files are received and processed. The integrity checks for both files were not being verified correctly.

Note that the lack of verification of the packfile checksum has no impact on the trust relationship between the client and server, which is enforced based on the protocol being used (e.g. TLS in the case of https:// or known hosts for ssh://). In other words, the packfile checksum verification does not provide any security benefits when connecting to a malicious or compromised Git server.

Patches

Users should upgrade to v5.16.5, or the latest v6 pseudo-version, in order to mitigate this vulnerability.

Workarounds

In case updating to a fixed version of go-git is not possible, users can run git fsck from the git cli to check for data corruption on a given repository.

Vulnerability from github – Published: 2025-06-27 16:24 – Updated: 2025-06-27 16:24

Summary

mapstructure May Leak Sensitive Information in Logs When Processing Malformed Data

Details

Summary

Use of this library in a security-critical context may result in leaking sensitive information, if used to process sensitive fields.

Details

OpenBao (and presumably HashiCorp Vault) have surfaced error messages from mapstructure as follows:

https://github.com/openbao/openbao/blob/98c3a59c040efca724353ca46ca79bd5cdbab920/sdk/framework/field_data.go#L43-L50

            _, _, err := d.getPrimitive(field, schema)
            if err != nil {
                return fmt.Errorf("error converting input for field %q: %w", field, err)
            }

where this calls mapstructure.WeakDecode(...): https://github.com/openbao/openbao/blob/98c3a59c040efca724353ca46ca79bd5cdbab920/sdk/framework/field_data.go#L181-L193


func (d *FieldData) getPrimitive(k string, schema *FieldSchema) (interface{}, bool, error) {
    raw, ok := d.Raw[k]
    if !ok {
        return nil, false, nil
    }

    switch t := schema.Type; t {
    case TypeBool:
        var result bool
        if err := mapstructure.WeakDecode(raw, &result); err != nil {
            return nil, false, err
        }
        return result, true, nil

Notably, WeakDecode(...) eventually calls one of the decode helpers, which surfaces the original value:

https://github.com/go-viper/mapstructure/blob/1a66224d5e54d8757f63bd66339cf764c3292c21/mapstructure.go#L679-L686

https://github.com/go-viper/mapstructure/blob/1a66224d5e54d8757f63bd66339cf764c3292c21/mapstructure.go#L726-L730

https://github.com/go-viper/mapstructure/blob/1a66224d5e54d8757f63bd66339cf764c3292c21/mapstructure.go#L783-L787

& more.

PoC

To reproduce with OpenBao:

$ podman run -p 8300:8300 openbao/openbao:latest server -dev -dev-root-token-id=root -dev-listen-address=0.0.0.0:8300

and in a new tab:

$ BAO_TOKEN=root BAO_ADDR=http://localhost:8300 bao auth enable userpass
Success! Enabled userpass auth method at: userpass/
$ curl -X PUT -H "X-Vault-Request: true" -H "X-Vault-Token: root" -d '{"password":{"asdf":"my-sensitive-value"}}' "http://localhost:8300/v1/auth/userpass/users/adsf"
{"errors":["error converting input for field \"password\": '' expected type 'string', got unconvertible type 'map[string]interface {}', value: 'map[asdf:my-sensitive-value]'"]}

Impact

This was rated 4.5 Medium by HashiCorp in the past iteration.

Vulnerability from github – Published: 2026-02-18 22:37 – Updated: 2026-02-20 16:46

Summary

filippo.io/edwards25519 MultiScalarMult produces invalid results or undefined behavior if receiver is not the identity

Details

(*Point).MultiScalarMult failed to initialize its receiver.

If the method was called on an initialized point that is not the identity point, MultiScalarMult produced an incorrect result.

If the method was called on an uninitialized point, the behavior was undefined. In particular, if the receiver was the zero value, MultiScalarMult returned an invalid point that compared Equal to every point.

Note that MultiScalarMult is a rarely used advanced API. For example, if you only depend on filippo.io/edwards25519 via github.com/go-sql-driver/mysql, you are not affected. If you were notified of this issue despite not being affected, consider switching to a vulnerability scanner that is more precise and respectful of your attention, like govulncheck.

Severity ?

Vulnerability from github – Published: 2026-03-18 20:10 – Updated: 2026-03-25 18:12

Summary

gRPC-Go has an authorization bypass via missing leading slash in :path

Details

Impact

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.

CVE-2026-27142 (GCVE-0-2026-27142)

Vulnerability from cvelistv5 – Published: 2026-03-06 21:28 – Updated: 2026-03-16 15:21

Title

URLs in meta content attribute actions are not escaped in html/template

Summary

Actions which insert URLs into the content attribute of HTML meta tags are not escaped. This can allow XSS if the meta tag also has an http-equiv attribute with the value "refresh". A new GODEBUG setting has been added, htmlmetacontenturlescape, which can be used to disable escaping URLs in actions in the meta content attribute which follow "url=" by setting htmlmetacontenturlescape=0.

CVE-2026-25934 (GCVE-0-2026-25934)

Vulnerability from cvelistv5 – Published: 2026-02-09 22:13 – Updated: 2026-02-11 21:23

Title

go-git improperly verifies data integrity values for .idx and .pack files

Summary

go-git is a highly extensible git implementation library written in pure Go. Prior to 5.16.5, a vulnerability was discovered in go-git whereby data integrity values for .pack and .idx files were not properly verified. This resulted in go-git potentially consuming corrupted files, which would likely result in unexpected errors such as object not found. For context, clients fetch packfiles from upstream Git servers. Those files contain a checksum of their contents, so that clients can perform integrity checks before consuming it. The pack indexes (.idx) are generated locally by go-git, or the git cli, when new .pack files are received and processed. The integrity checks for both files were not being verified correctly. This vulnerability is fixed in 5.16.5.

Severity ?

4.3 (Medium)

This resulted in go-git potentially consuming corrupted files, which would likely result in unexpected errors such as object not found. For context, clients fetch packfiles from upstream Git servers. Those files contain a checksum of their contents, so that clients can perform integrity checks before consuming it. The pack indexes (.idx) are generated locally by go-git, or the git cli, when new .pack files are received and processed. The integrity checks for both files were not being verified correctly. This vulnerability is fixed in 5.16.5."

CVE-2025-61729 (GCVE-0-2025-61729)

Vulnerability from cvelistv5 – Published: 2025-12-02 18:54 – Updated: 2025-12-03 19:37

Title

Excessive resource consumption when printing error string for host certificate validation in crypto/x509

Summary

Within HostnameError.Error(), when constructing an error string, there is no limit to the number of hosts that will be printed out. Furthermore, the error string is constructed by repeated string concatenation, leading to quadratic runtime. Therefore, a certificate provided by a malicious actor can result in excessive resource consumption.

Severity ?

7.5 (High)

CVE-2026-27139 (GCVE-0-2026-27139)

Vulnerability from cvelistv5 – Published: 2026-03-06 21:28 – Updated: 2026-03-09 14:53

Title

FileInfo can escape from a Root in os

Summary

On Unix platforms, when listing the contents of a directory using File.ReadDir or File.Readdir the returned FileInfo could reference a file outside of the Root in which the File was opened. The impact of this escape is limited to reading metadata provided by lstat from arbitrary locations on the filesystem without permitting reading or writing files outside the root.

Severity ?

2.5 (Low)
