Summary

Shield Security for WordPress, all versions through 22.3.2, contains a stored cross-site scripting flaw in its traffic log (CWE-79). The REQUEST_URI value is stored without sanitization or escaping, so the hidden path column renders attacker-supplied HTML as live page elements. An unauthenticated remote attacker can inject scripts that run in the browser of any user who opens an affected page.

Description from the CNA

The Shield Security – Smart Bot Blocking, Brute-Force Login Protection & File Scanning plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'REQUEST_URI' parameter in all versions up to, and including, 22.3.2 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 hidden 'path' column in ForTraffic.php lacks a client-side render function, so DataTables builds its cell via innerHTML, causing stored HTML in the path value to be parsed into live DOM nodes; a prior partial fix in version 18.5.8 added esc_html() only to the visible 'page' column, leaving the hidden 'path' field unescaped and exploitable through version 22.2.6.
