Understand the problem

What is the problem?

The product creates an immutable text string using string concatenation operations.

Extended description

When building a string via a looping feature (e.g., a FOR or WHILE loop), the use of += to append to the existing string will result in the creation of a new object with each iteration, which can be inefficient in comparison with use of text buffer data elements.

Reduce Performance

Affected security scopes: Other

This issue can make the product perform more slowly. If the relevant code is reachable by an attacker, then this could be influenced to create performance problem.

Defence

How is it prevented and fixed?

  • Follow secure coding guidelines for input handling and boundary checking.
  • Enforce strict security reviews and automated static analysis (SAST) checks.
