If you run ManageWP Worker
What to do now
- Check your version. In WordPress, go to Plugins and look under ManageWP Worker. Compare it with the affected versions above.
- Update to 4.9.37 or later. Take a backup first, then update. If the update breaks something, you can restore the backup while you work out why.
- Check the rest of your site. One outdated plugin is rarely the only one. Our free security check looks at your WordPress version, and the plugins and theme it can see from the outside, for known flaws and emails you a report.
Pressfort keeps your plugins up to date for you, testing each update on a copy of your site first, and its virtual patching blocks attacks on newly disclosed flaws, often before a fix is out. If your site does get hacked, two clean-ups a year are included, with a developer stepping in when needed. See how it works.
