**Stack:** Go

- Prevalence: High Frequently exploited
- Impact: High 3 high-severity rules
- Prevention: Documented 3 fix examples

**OWASP:** Broken Access Control (A01:2021-Broken Access Control) - #1

## Description

Assuming a user with a given identity, authorization is the process of determining whether that user can access a given resource. When authorization checks are completely missing, any authenticated user can access protected resources.

## Prevention

Prevention strategies for Missing Authorization based on 1 Shoulder detection rules.

### Go

Require human approval for sensitive operations and limit agent loop iterations

## Warning Signs

- [HIGH] Excessive LLM agency detected: ...
- [HIGH] LLM implementations with excessive autonomy allowing destructive operations without human approval

## Consequences

- Read Application Data
- Modify Application Data
- Gain Privileges

## Mitigations

- Implement authorization checks for all protected resources
- Use a centralized authorization mechanism
- Follow the principle of deny by default

## Detection

- Total rules: 3
- Languages: go, javascript, typescript, python

## Rules by Language

### Go (1 rules)

- **LLM Excessive Agency** [HIGH]: Detects LLM implementations with excessive autonomy allowing destructive operations without human approval.
  - Remediation: Require human approval for sensitive operations and add iteration limits.

```go
if sensitiveOperations[toolName] {
    queueForApproval(toolCall)
}
```
