To challenge false positive findings for insecure storage vulnerabilities in Salesforce, developers should: 1. **Prepare a False Positive Document**: Include detailed justifications and references explaining why the reported issue is invalid. For example, if sensitive data (e.g., `client_API_ID`) is non-critical or encrypted with a key stored in protected custom settings, document this clearly. 2. **Ensure Secure Storage**: Verify that sensitive data (e.g., `client_secret_key`) is securely stored in protected custom settings. 3. **Remove Unused Code**: If the flagged code is no longer in use, remove it from the package or provide evidence of its irrelevance. 4. **Submit Documentation**: Use the appropriate case or partner portal to submit the false positive document for review and resolution. This process ensures a thorough review and helps address any misunderstandings.
