About the WordPress Version Checker
WordPress leaves version hints in a few public places - the generator meta tag, the readme.html file, and the version query string on core assets. This tool reads those to estimate which core release a site is running.
Running an outdated core is one of the most common causes of a hacked WordPress site. Checking the version tells you at a glance whether a site is current or overdue for an update.
How to use it
- 1Enter the WordPress site's address.
- 2Run the check to see the detected core version and how it compares to the latest release.
- 3If it's behind, update core (after a backup) - ideally on staging first.
What it checks
- Detected version
- The core version inferred from public markup and asset fingerprints.
- Latest release
- The current WordPress version, so you can see the gap.
- Status
- Whether the site is up to date, one minor behind, or on an outdated branch.
- Exposure
- Whether the version is publicly advertised - many hosts hide it to reduce targeting.
Frequently asked questions
Why does the version sometimes show as hidden?
Security-conscious sites remove the generator tag and readme.html, so the exact version can't be read from outside - which is a good sign.
Is an outdated version really a risk?
Yes. Most mass WordPress attacks target known vulnerabilities in old core, themes, or plugins. Staying current is the single biggest protection.
How often should I update WordPress?
Apply security releases quickly, and test minor/major updates on a staging copy before pushing them to production.
Run WordPress on infrastructure built for it.
