• Off-by-one errors
• Race conditions
• Incorrect conditionals
• Unhandled edge cases

Security Risks

Vulnerabilities that could be exploited:

• SQL injection
• XSS (Cross-Site Scripting)
• CSRF vulnerabilities
• Authentication bypasses
• Hardcoded secrets

Architecture Notes

Structural issues at a higher level:

• Circular dependencies
• Inappropriate coupling
• Violation of separation of concerns
• Inconsistent patterns within the codebase
