See how wp statistics compares to other vendors in security performance
The WP Statistics plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the URL search parameter in all versions up to, and including, 14.5 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.
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.
The WP Statistics – Simple, privacy-friendly Google Analytics alternative plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'utmcampaign' parameter in all versions up to, and including, 14.16.8 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. The payload can be planted without authentication via the public /wp-statistics/v2/hit REST endpoint, because the required signature is exposed on the public homepage and a base64-encoded pageuri POST parameter overrides the previously sanitized REQUESTURI, allowing the malicious utmcampaign value to bypass sanitization and be stored in the database.
Cross-site scripting vulnerability in WP Statistics version 12.0.4 and earlier allows remote attackers to inject arbitrary web script or HTML via specially crafted HTTP Referer headers.
The WP Statistics – The Most Popular Privacy-Friendly Analytics Plugin plugin for WordPress is vulnerable to unauthorized modification of data due to a missing capability check on the 'optionUpdater' function in all versions up to, and including, 14.13.3. This makes it possible for authenticated attackers, with Subscriber-level access and above, to update arbitrary plugin settings.
