"Multiple CVE(s) were discovered in the src:wordpress package.

CVE-2020-11026

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.

CVE-2020-11027

A password reset link emailed to a user does not expire upon changing
the user password. Access would be needed to the email account of the
user by a malicious party for successful execution.

CVE-2020-11028

Some private posts, which were previously public, can result in
unauthenticated disclosure under a specific set of conditions.

CVE-2020-11029

A vulnerability in the stats() method of class-wp-object-cache.php can
be exploited to execute cross-site scripting (XSS) attacks.

For Debian 8 'Jessie', these problems have been fixed in version
4.1.30+dfsg-0+deb8u1.

We recommend that you upgrade your wordpress packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
