CVE-2022-4541

Description

The WordPress Visitors plugin for WordPress is vulnerable to Stored Cross-Site Scripting via a spoofed HTTP Header value in versions up to, and including, 1.0 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 the nm_vistior page.
