WordPress as a platform has been a solid, secure application over the years. The few times a vulnerability has been found, the WP team has been super-fast to patch it, publicize it, and take care of business.
That said, there are two major areas where WordPress lacks in security:
There are so many plugins for WordPress, which is part of what makes it so great. However, those plugins can also present attack vectors, and we see evidence of this almost every day.
It was just revealed that most WP users have very little understanding of the risk they are lending to their own websites. Not updating plugins, not updating WP itself, and not doing backups, are the most easily fixed things that people tend to not do.
This puts WP websites at risk, lets them get hacked, and gives WordPress as a whole a bad wrap.
The survey of 503 WordPress users, which took place online during February this year, revealed that WordPress users are more exposed to security problems than expected. In total, 54 percent of respondents said they updated WordPress between once a week and every few weeks, and yet only 24 percent back their websites up — and only 23 percent have received training in the use of tools such as backup plugins.
On that note, I thought I’d mention that the most popular SEO plugin for WordPress, Yoast’s WP SEO, has a new, major vulnerability in it. GO UPDATE!
