Why This Matters

This weakness class (Observable Behavioral Discrepancy) creates a concrete exploit surface: the rule searches for the concrete source-level patterns most commonly associated with CWE-205 and surfaces them for review. Each finding should be evaluated in context — the rule catches the pattern, not the context.

What Gets Flagged

// FLAGGED: contains 'if user:' pattern
if user:

Remediation

  1. Review each flagged line and determine whether the pattern represents a real instance of CWE-205 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-205 comment on the line.
  4. Ensure equivalent test coverage exists to prevent regression.
