"**WordPress 4.7.3 is now available**. This is a security release for
all previous versions and we strongly encourage you to update your
sites immediately.

WordPress versions 4.7.2 and earlier are affected by six security
issues :

  - Cross-site scripting (XSS) via media file metadata.
    Reported by Chris Andrè Dale, Yorick Koster, and
    Simon P. Briggs.

  - Control characters can trick redirect URL validation.
    Reported by Daniel Chatfield.

  - Unintended files can be deleted by administrators using
    the plugin deletion functionality. Reported by xuliang.

  - Cross-site scripting (XSS) via video URL in YouTube
    embeds. Reported by Marc Montpas.

  - Cross-site scripting (XSS) via taxonomy term names.
    Reported by Delta.

  - Cross-site request forgery (CSRF) in Press This leading
    to excessive use of server resources. Reported by Sipke
    Mellema.

Thank you to the reporters for practicing responsible disclosure.

In addition to the security issues above, WordPress 4.7.3 contains 39
maintenance fixes to the 4.7 release series. For more information, see
the [release notes](https://codex.wordpress.org/Version_4.7.3) or
consult the [list of
changes](https://core.trac.wordpress.org/query?status=closed&milestone
=4.7.3&group=component&col=id&col=summary&col=component&col=status&col
=owner&col=type&col=priority&col=keywords&order=priority).

Note that Tenable Network Security has extracted the preceding
description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as
possible without introducing additional issues."
