Security database references:

In Mitre's CVE dictionary: CVE-2020-13666, CVE-2020-13671.

More information:

Two vulnerabilities were discovered in Drupal, a fully-featured content management framework.

• CVE-2020-13666

  The Drupal AJAX API did not disable JSONP by default, which could lead to cross-site scripting.

  For setups that relied on Drupal's AJAX API for JSONP requests, either JSONP will need to be reenabled, or the jQuery AJAX API will have to be used instead.

  See the upstream advisory for more details: https://www.drupal.org/sa-core-2020-007

• CVE-2020-13671

  Drupal failed to sanitize filenames on uploaded files, which could lead to those files being served as the wrong MIME type, or being executed depending on the server configuration.

  It is also recommended to check previously uploaded files for malicious extensions. For more details see the upstream advisory: https://www.drupal.org/sa-core-2020-012

For Debian 9 stretch, these problems have been fixed in version 7.52-2+deb9u12.

We recommend that you upgrade your drupal7 packages.
