API Enhanced Broken Object Level Authorization

Remediation

To mitigate Enhanced Broken Object Level Authorization vulnerabilities, implement the following security measures:

1. Object-Level Access Controls: Implement comprehensive authorization checks for each object access to ensure users can only access their own resources.

2. Resource Ownership Validation: Validate resource ownership before allowing access to prevent horizontal privilege escalation.

3. Consistent Authorization: Apply authorization checks consistently across all API endpoints that access objects or resources.

4. Audit Logging: Implement comprehensive audit logging for object access attempts to detect unauthorized access patterns.

About

Risks

Enhanced BOLA vulnerabilities can result in:

• Unauthorized access to user objects and data
• Horizontal privilege escalation attacks
• Data exposure across user boundaries
• Violation of data privacy and isolation
• Potential for large-scale data breaches
