How secure is your WordPress installation?

Recommended Posts

I have been using WordPress for this blog for several years and always thought my setup was reasonably secure. Turns out that there is something called the WordPress REST API which allows to get quite a lot information about the installation without any security at all.

Read on in the blog post.

I'm not a WP expert, so it's nice to see a blog where the the problem is explained and solution is simple: download plugin+upload+activate. Simple, thanks!

I don't see how enabling basic authentication would make the web site more secure.

The password is sent as plain in the headers, just base-64 encoded, so there is no benefit.
If just adding a password would make something more secure... it would have been used everywhere.


The best security advice, which is not on your blog post, is to maintain your WP installation up-to-date, with all the security fixes.

My blog post is not meant as a general security advice for WordPress. I'm not qualified to give that. It just highlights one particular problem which apparently many overlook. As for authentication: It is only as secure as the transport protocol, so if the installation uses plain http its not much. It does prevent automated data harvesting by simple bots though.

Install WordFence (the are free and paid version) and keep the number of plug-ins to a minimum.

The description scares me a little bit... almost feels like it sends an assassin to anybody trying to access my website... 🙂

 I wonder if that also leaks these things?

No, it doesn't.
