What are the accepted methods for mitigating a CSRF vulnerability in a Lightning Web Component?
Answer
To mitigate CSRF vulnerabilities in Lightning Web Components:
1. Avoid performing state changes or DML operations in an Apex controller during the component's instantiation.
2. Trigger state changes explicitly through user actions, like button clicks.
3. Use Salesforce's built-in CSRF protection mechanisms for all form requests and state changes.
For more detailed guidance, refer to secure server-side development practices.

Reasoning
The FAQ content is accurate and well-structured, providing three clear mitigation strategies for CSRF vulnerabilities in Lightning Web Components. No significant changes are needed as the advice aligns with security best practices. I selected the ApexCSRF rule because it directly relates to the FAQ's focus on CSRF (Cross-Site Request Forgery) vulnerabilities. The FAQ discusses avoiding state changes during component instantiation and ensuring state changes are triggered through explicit user actions - these are core CSRF prevention techniques that the ApexCSRF rule is designed to detect violations of. The rule helps identify when Apex controllers might be vulnerable to CSRF attacks by performing state-changing operations without proper protection, which directly corresponds to the FAQ's guidance on proper CSRF mitigation in Lightning Web Components.
