Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

The WP Statistics – The Most Popular Privacy-Friendly Analytics Plugin plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the User-Agent Header in all versions up to, and including, 14.5.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
