Add more files extensions with a new field in your Medias Settings.
<a href="http://irz.fr/add-more-files-extensions/" rel="nofollow ugc">You can check the dev page</a>
You just need to insert your extensions in <code>Settings > Medias > Uploading Files</code> separate by a space (ex : ‘exe pdf rar’), and the plugin does the rest.
This plugin is in french but the translation in english is in progress.

WordPress relies mostly on name-based validation when deciding whether or not to allow a particular file, leaving the door open for various kinds of attacks.

<li>SVG sanitization (if SVG uploads have been independently allowed);</li>
<li>File upload validation debugger;</li>
<li>Fixes issues related to <a href="https://core.trac.wordpress.org/ticket/40175" rel="nofollow ugc">#40175</a> that have been present since WordPress <code>4.7.1</code>.</li>
<li>Fixes ambiguous media extensions <a href="https://core.trac.wordpress.org/ticket/40921" rel="nofollow ugc">#40921</a></li>
</ul>

Please note: it is not safe to run WordPress atop a version of PHP that has reached its <a href="http://php.net/supported-versions.php" rel="nofollow ugc">End of Life</a>. Future releases of this plugin might, out of necessity, drop support for old, unmaintained versions of PHP. To ensure you continue to receive plugin updates, bug fixes, and new features, just make sure PHP is kept up-to-date. 🙂
