cwe CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')
published Feb 18, 2026
The StatCounter – Free Real Time Visitor Stats plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the user's Nickname in all versions up to, and including, 2.1.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with Contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
