The review process evaluates vulnerabilities across your entire solution, and addressing these issues is necessary to ensure your application's security.
Reasoning
The original answer was clear but could be more conversational and concise per the brand guidelines. I made minor improvements: changed 'Am I responsible' to 'you're responsible' for a more conversational tone, simplified 'they are not part of' to 'they're not part of', and changed 'the security of your application' to 'your application's security' for better flow. These changes maintain all the original information while making the text more natural and direct. The selected security rules relate to the FAQ because they represent the types of security issues that developers must fix during the AppExchange Security Review regardless of whether they're in custom code or third-party components: ApexCRUDViolation relates to CRUD violations that must be fixed throughout the solution; ApexSharingViolations covers sharing rule violations across all code; ApexSOQLInjection addresses SQL injection vulnerabilities anywhere in the codebase; ApexXSSFromEscapeFalse and ApexXSSFromURLParam cover XSS vulnerabilities that must be addressed regardless of origin; VfCsrf and VfUnescapeEl address Visualforce security issues that affect the entire solution; LibraryWithKnown*SeverityVulnerability rules cover third-party library vulnerabilities that developers must address even though they didn't write that code - these directly exemplify the FAQ's point about responsibility for non-custom code issues.
