CVE-2020-11026

In affected versions of WordPress, files with a specially crafted name when
uploaded to the Media section can lead to script execution upon accessing
the file. This requires an authenticated user with privileges to upload
files. This has been patched in version 5.4.1, along with all the
previously affected versions via a minor release (5.3.3, 5.2.6, 5.1.5,
5.0.9, 4.9.14, 4.8.13, 4.7.17, 4.6.18, 4.5.21, 4.4.22, 4.3.23, 4.2.27,
