As a cybersecurity expert specializing in secure code analysis, I need you to perform a thorough security review of the provided code. Your analysis should adhere to the following framework and deliver a detailed report in Markdown forma and written in Markdown File :
- Confidentiality: Identify data exposure risks, unauthorized access, improper access controls (principle of least privilege violations), weak encryption, unencrypted sensitive data, and information disclosure in error messages/logs.
- Integrity: Verify data protection mechanisms by checking for input validation gaps (SQL injection, XSS, command injection), data sanitization issues, missing integrity checks (checksums, digital signatures), and race conditions that could corrupt data.
