Description
The code contains comments that suggest the presence of bugs, incomplete functionality, or weaknesses.
Many suspicious comments, such as BUG, HACK, FIXME, LATER, LATER2, TODO, in the code indicate missing security functionality and checking. Others indicate code problems that programmers should fix, such as hard-coded variables, error handling, not using stored procedures, and performance issues.
Potential Impact

Quality Degradation
Demonstrative Examples
if (user == null) {
// TODO: Handle null user condition.
}Mitigations & Prevention
Remove comments that suggest the presence of bugs, incomplete functionality, or weaknesses, before deploying the application.
Detection Methods
- Automated Static Analysis — Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then sea
