Summary
The Meta Box WordPress plugin, a framework used for building custom fields and dynamic websites, is affected in all versions up to and including 5.15.2. An authenticated user with low-level access, such as a subscriber, could store malicious scripts through a crafted field key, which would then run in the browsers of anyone who views the affected page, potentially allowing session hijacking or actions taken on behalf of other users.

Read the original description
The Meta Box – A Framework for Dynamic Websites plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'profile_background[<attacker-chosen key>]' parameter in all versions up to, and including, 5.15.2 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with subscriber-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Exploitability depends on a consuming plugin or theme built on Meta Box that exposes the background field to lower-privileged users and renders stored values via the rwmb_the_value()/format_single_value() pattern; the effective minimum privilege is whatever role that consumer permits, demonstrated at Subscriber level.
