Guidance

Get reliable results

  1. 1Use framework-native escaping for production templates
  2. 2Decode entities before comparing readable text
  3. 3Do not treat entity decoding as an XSS defense
Entity conversion does not sanitize full HTML and cannot replace a content security policy or a dedicated HTML sanitizer.
