Backuply: SQL injection
What's happening
Backuply has a SQL injection flaw in every version up to 1.5.8 (included): an attacker can read or change the site's database, including user and customer data. It requires a user account, even the most basic one (subscriber): it matters most on sites with open registration, such as shops and membership sites. More than 600,000 websites use it.
What to do
Update Backuply to version 1.5.9 or later (Dashboard → Plugins in WordPress). If you can't update yet, deactivate it until you can.
