WP Super Cache & W3 Total Cache Users: Are Your Sites Vulnerable?

Are your sites vulnerable?

Not updating vulnerable plugins is one of the biggest mistakes anyone running WordPress can make. And it seems some of the world’s most visited sites are making that exact mistake. … Are you?

A number of weeks ago, perhaps the two most popular caching plugins, WP Super Cache and W3 Total Cache, both updated their code to patch a security vulnerability. HackerTarget.com reports that a quick check of the top 100,000 sites reveals that less than 50% of those sites that run W3 Total Cache have updated their plugins to the latest secure version.

The exact numbers for WP Super Cache are not known, but it’s not unreasonable to think they’re similarly dismal.

The bigger you are, the harder you fall. But you don’t have to be big to be vulnerable. If you’re running one of these popular plugins, it might serve you to make sure your copy is up to date.

Update! Update! Always, always update!
