A flaw was found in github.com/go-viper/mapstructure/v2, in the field processing component using mapstructure.WeakDecode. This vulnerability allows information disclosure through detailed error messages that may leak sensitive input values via malformed user-supplied data processed in security-critical contexts.

GHSA-2464-8j7c-4cjm — go-viper's mapstructure May Leak Sensitive Information in Logs When Processing Malformed Data

Affected: Go: github.com/go-viper/mapstructure/v2

### 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

```go _, _, 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

```go

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:
