Why This Matters

Each finding should be evaluated in context — the rule catches the pattern, not the context.

What Gets Flagged

// FLAGGED: contains 'throw new UnsupportedOperationException' pattern
throw new UnsupportedOperationException

Remediation

  1. Review each flagged line and determine whether the pattern represents a real instance of CWE-447 or a false positive.
  2. Replace the flagged construct with a documented safe alternative appropriate to your language and framework.
  3. For confirmed false positives, add a # vulnetix-ignore: VNX-447 comment on the line.
  4. Ensure equivalent test coverage exists to prevent regression.
