How to Fix Outdated and Vulnerable WordPress Plugins
Outdated plugins are the number-one way WordPress sites get hacked. A single vulnerable plugin can expose the whole site to XSS, SQLi, or remote code execution. Keeping them current — and dropping the ones nobody maintains — closes most of your attack surface.
- 1
Update every plugin, theme, and core
Apply all available updates. Enable automatic updates for plugins you trust, and check the site after major updates.
- 2
Remove abandoned plugins
A plugin that hasn't been updated in 1–2 years (or was removed from the directory) will never get security fixes. Find a maintained alternative and delete it.
- 3
Check plugins against known vulnerabilities
Before trusting a plugin, look up its security history. Our vulnerability database tracks known issues for thousands of plugins and themes.
- 4
Scan regularly
New vulnerabilities are disclosed weekly. Run an external scan after every update so you catch newly-vulnerable versions fast.

More fix guides
Sanitize input, escape output, patch vulnerable plugins, and add a Content-Security-Policy.
Patch vulnerable plugins and use $wpdb->prepare() for every query with user input.
Block xmlrpc.php unless you need it — it enables brute-force amplification and pingback DDoS.
Add HSTS, CSP, X-Frame-Options, X-Content-Type-Options, and Referrer-Policy.
