WordPress 2.8.6 Release – 2 Security Fixes

by George Serradinho on November 13, 2009

I woke this morning to a notification about a new version of WordPress, it’s now 2.8.6. This version is for sites that have multi-authors. If you don’t have other authors, then I still think you should upgrade.

Many sites have opened up to the idea of guest posts and this release will help those sites in protecting themselves. One would rather be safe than sorry.

Multi Authors

The 2 fixes are:

  1. An XSS vulnerability in Press This discovered by Benjamin Flesch.
  2. Problem discovered by Dawid Golunski, is an issue with sanitizing uploaded file names that can be exploited in certain Apache configurations.

Thanks to Benjamin and Dawid for finding and reporting these issues.

Please remember to backup of your database and files before upgrading.

Get WordPress version 2.8.6 now

P.S. I upgraded automatically and had no problems at all.

Final Thought

Would like to know if you have upgraded to the new version already? Are you using an old version? Did you upgrade manually or automatically? Do your site a multi-author site?

@Anand – try and keep your WordPress up to date, otherwise you run the risk which could cost you later.

George, I have heard that it is always better to wait for a few days before upgrading since you give enough time for plugin developers to upgrade it sufficiently…

But you are right, and I have already upgraded to 2.8.6 on all my three blogs.

@Sire – yes, they made it easier now with the automated upgrade. Funny thing is that I have never had issues with upgrading. I sometimes find users who had problems, etc. Thank God I have been blessed with not having issues :)

I’ve only ever had one issue, but that was because of something I did. The auto upgrade feature takes that problem away.

@Vivek – I use to just backup my database, now I backup my database as well as my theme files. This is just to ensure that if something went wrong, that I had a backup to refer to.

@Gabe – you are correct in upgrading. I have seen users still on old versions, which might result in a security breach. There are some users who don’t want to upgrade as they have customized plugins that were created and don’t know if the upgrade will work or break their site.

I upgraded and everything seems ok too. Needless to mention that some plug-ins will inform us to update too and this depends on what plug-ins we installed. Thanks Geroge for the update

I’ll have to ask my IT gal, she just upgraded me to 2.5 (I think.) I will probably hold off a while.

One thing I DO want to get is Lightbox2 for the photos in my posts to make ‘em real real big. You know much about that?

Hopefully everyone read it here first :)

@Extreme John – if you don’t have guest bloggers then you don’t have to update. I do understand your frustration, but updates will continue as long as users try and break sites. It’s for our own safety buddy.

@CLP – just wanted to say that your comments are landing in my spam because of the url you are using. I don’t mind the comments, but please don’t use the url you always use on my site as I always edit it. I’m not going to say the url, but you know exactly what I’m talking about.

As for your comment – I don’t think it’s a good idea to be on WP 2.7 as there have been many improvements and security patches. You will suffer more that you are way behind on updates. I urge you to rather make a full backup of your database and files/images and upgrade.

I will update later today. But, I really wish that Wpress would also start releasing incremental update files. I am sure that most of the files from v2.85 haven’t even been touched. But, I would have to upload them all – which takes a 15-20 minutes.
And the built in auto-update never works for me.

@Pallab – not to be funny, but why so long? Even if I had to copy all the WP files across, it would not take more than 3 minutes and that includes uploading my Thesis theme folder as well. Please explain in detail why so long?
