FAQ-001622 - SQL Injection and Input Validation / Security Review and Vulnerability Assessment

A dynamic SOQL query might still be flagged as a vulnerability after applying fixes for the following reasons: 1. **Incomplete Input Sanitization**: If user-supplied input isn't fully sanitized or bind variables aren't used, the query may still be vulnerable to SOQL injection. 2. **Missing CRUD/FLS Checks**: Failing to implement proper Create, Read, Update, and Delete (CRUD) or Field-Level Security (FLS) checks can expose sensitive data or allow unauthorized operations. 3. **Residual Patterns**: Security scanning tools might detect patterns that resemble vulnerabilities, even if the issue has been addressed. If you believe the query is secure, document the applied fixes and provide a false positive report for clarification during the review process.

The FAQ content is generally accurate but could benefit from minor clarifications. I made small improvements to enhance clarity: added 'to SOQL injection' to point 1 to be more specific about the vulnerability type, and added 'or allow unauthorized operations' to point 2 to better reflect the full scope of CRUD/FLS issues. These changes make the explanations more precise without altering the structure or adding new points. For security rules selection: - ApexSOQLInjection: This rule directly relates to the FAQ's discussion of dynamic SOQL queries and input sanitization. The FAQ specifically mentions 'user-supplied input' and 'bind variables' which are core concepts in SOQL injection prevention. - ApexCRUDViolation: The FAQ explicitly discusses 'CRUD or Field-Level Security (FLS) checks' in point 2, which directly corresponds to this rule that detects missing CRUD/FLS enforcement. - ApexSharingViolations: While not explicitly mentioned in the FAQ, sharing violations are closely related to the security context of dynamic SOQL queries and data exposure concerns mentioned in the answer, making this rule relevant to the overall topic.
