Arbitrary file deletion in WordPress plugins

Arbitrary file deletion lets an attacker delete files on the server that the plugin should never touch.

Deleting the wrong file breaks the site, but the bigger risk is wp-config.php: if it is deleted, WordPress shows the install screen, and whoever gets there first can connect the site to their own database and take over.

What to do: update the plugin. Keep a recent off-site backup so you can restore files quickly.

Worried a plugin bug was used on your site?

The free scan reads the public side of your site and looks for spam pages, hidden redirects, injected scripts and blacklist entries. No login, no install, about a minute.
