FAQ-000239 - CSRF and DML Security Issues / Security Review and Documentation

To identify and fix CSRF vulnerabilities that cause repeated AppExchange Security Review failures, follow these steps: 1. **Understand the Vulnerabilities**: Review the security review report to pinpoint specific CSRF issues. These often involve DML operations triggered on page load without user interaction. 2. **Add User Interaction**: Ensure sensitive actions, like uploads or DML operations, require explicit user authorization through buttons or confirmation prompts. 3. **Thorough Testing**: Use tools like Salesforce Code Analyzer and manual testing to identify and resolve CSRF vulnerabilities across your solution. 4. **Apply Security Best Practices**: Implement proper session handling and anti-CSRF tokens to secure your solution. 5. **Resubmit for Review**: After fixing the issues, rerun scanner tools, update scan reports, and document any false positives. Submit the revised solution via the AppExchange Partner Console. 6. **Seek Expert Guidance**: If needed, schedule a session with the Product Security team through the Partner Security Portal for additional support. By addressing these steps, you'll improve your chances of passing the security review.

For ApexCSRF rule selection: This rule directly relates to the FAQ's core topic since it detects CSRF vulnerabilities in Apex code, which is exactly what the FAQ discusses when mentioning 'DML operations triggered on page load without user interaction' and the need for 'explicit user authorization.' The FAQ's guidance on adding user interaction and implementing anti-CSRF tokens directly addresses what this rule is designed to catch. For VfCsrf rule selection: This rule is highly relevant because it identifies CSRF vulnerabilities in Visualforce pages, which is a common source of the security review failures the FAQ addresses. When the FAQ mentions 'sensitive actions, like uploads or DML operations' requiring user authorization, this often applies to Visualforce pages where the VfCsrf rule would flag violations.
