What is CVE-2020-13666?

A cross-site scripting (XSS) vulnerability exists in Drupal Core due to the AJAX API not disabling JSONP by default. This oversight can allow attackers to inject malicious scripts via specially crafted content. Websites using affected versions of Drupal could be exploited, potentially leading to unauthorized actions being performed on behalf of users. It is crucial for site administrators to update to the latest versions to mitigate this risk.

Drupal Core 7.x < 7.73

Drupal Core 8.8.x < 8.8.10
