A developer is aware that HTL comes out-of-the-box XSS protection, but the client has received a warning from the security audit team about a possible XSS vulnerability in one component. What is a potential cause of this problem?
Correct Answer: A
HTL (HTML Template Language) in AEM provides built-in XSS protection. However, XSS vulnerabilities can still arise if: * Unsafe Display Context: * If an "unsafe" display context is set for an HTL expression, it can disable the default XSS protection and expose the component to XSS vulnerabilities. Ensuring that the correct display context is used is critical for maintaining security. References: * AEM's HTL documentation outlines the display contexts and their impact on XSS protection. * Security best practices in AEM emphasize the importance of using safe display contexts to prevent XSS vulnerabilities.
