| baserproject/basercms | composer | <= 5.1.1 | 5.1.2 |
The vulnerability involves stored XSS in the Edit Email Form Settings feature. XSS typically occurs when user input is not sanitized on output. In MVC frameworks like baserCMS (CakePHP-based), controllers handle input processing, and views handle rendering. The edit action in EmailFormSettingsController likely fails to sanitize input before saving, while the associated view template (edit.ctp) may lack proper escaping (e.g., using <?= h($field) ?>). The high confidence in the view template stems from the prevalence of XSS via unescaped output in similar CMS systems. The medium confidence in the controller reflects uncertainty about input validation practices without explicit patch details.
