CVE-2023-1166 – USM Premium < 16.3 - Admin+ Stored XSS

https://notcve.org/view.php?id=CVE-2023-1166

The USM-Premium WordPress plugin before 16.3 does not sanitize and escape some of its settings, which could allow high-privilege users such as admin to perform Stored Cross-Site Scripting attacks even when the unfiltered_html capability is disallowed (for example, in multisite setup). The USM Premium plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in versions up to, and including, 16.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled. • https://wpscan.com/vulnerability/825eccf9-f351-4a5b-b238-9969141b94fa • CWE-79: Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') •
