# Direct Map Access on Thread-Safe Struct

- ID: go-direct-map-access
- Severity: HIGH
- CWE: Race Condition (CWE-362)
- Languages: Go

## Description

Direct access to map fields on structs that provide thread-safe accessor methods
can cause race conditions. Use the provided accessor methods instead.

## Detection Message

Direct access to map fields can cause race conditions in concurrent code.
Maps in Go are not thread-safe, and concurrent reads/writes can cause
runtime panics ("fatal error: concurrent map read and map write").


## Remediation

Use thread-safe accessor methods if available:
```go
// Instead of: value := obj.MapField["key"]
value, ok := obj.GetAttr("key")

// Instead of: obj.MapField["key"] = value
obj.SetAttr("key", value)
```

Or protect with mutex:
```go
mu.RLock()
value := obj.MapField["key"]
mu.RUnlock()
```
