About Xposer

Xposer/Patternd shows which product and version a website is running, and which known vulnerabilities apply to that version. Open the popup on a page, or type an address. The extension sends that address to patternd.io and shows the detected software, its version, the latest stable version when the API provides one, and known CVEs with severity and links. You need a patternd.io personal access token. Save it in the extension settings. It stays in browser storage on your device. A probe sends the site address and the token to patternd.io over HTTPS.
