Code scanning / CodeQL

Overly permissive regular expression range Medium

Suspicious character range that is equivalent to [A-Z\[\]^_`a-z].

Copilot Autofix AI 4 months ago

To fix the problem, we need to correct the regular expression to match only the intended characters. Specifically, we should replace the overly permissive range A-z with the correct ranges for uppercase and lowercase letters, which are A-Z and a-z, respectively.

  • General fix: Replace the A-z range with A-Za-z to ensure only alphabetic characters are matched.
  • Detailed fix: Modify the regular expression on line 219 in the testMethod to use A-Za-z instead of A-z.
  • Specific changes: Update the Pattern.compile call in the testMethod to use the corrected character range.
  • Requirements: No additional methods, imports, or definitions are needed to implement this change.
