Detection Guidance

To detect this XSS vulnerability in Drupal MathJax: LaTeX, inspect Drupal sites running versions 0.0.0 to 4.1.2. Check for user-supplied input rendered without proper sanitization in MathJax output. Manual review of page source or using browser developer tools to inspect rendered HTML for suspicious scripts is recommended.
