What does this scanner check?
It detects the WordPress core version and installed plugins/themes from a site's page source, then checks each against our own vulnerability database for known CVEs.
How does it detect installed plugins and themes without scanning every possible path?
WordPress includes a version query string (?ver=1.2.3) on each plugin/theme asset URL by default. Parsing the page source directly reveals the slug and exact version for everything actually loaded on the page — no path-guessing needed.
Why does this require authentication?
This tool fetches and analyses a live target. Authentication and target-ownership verification ensure users only scan infrastructure they control.
Where does the vulnerability data come from?
We maintain our own vulnerability database, refreshed automatically. Results are looked up against our own records, not fetched live from a third party at scan time.
