## Description

The CubeWP Framework plugin for WordPress is vulnerable to Stored Cross-Site Scripting via custom field values saved through the REST API (cubewp_user_meta, cubewp_post_meta and cubewp_term_meta) in all versions up to, and including, 1.1.31. This is due to insufficient input sanitization and output escaping: colour field values were placed raw into a style attribute, Business Hours day keys and times were concatenated into markup and attributes, and Google address values were output unescaped. This makes it possible for authenticated attackers, with subscriber-level access and above (for example through /wp/v2/users/me), to inject arbitrary web scripts that execute when a user views author or single pages, or when an administrator opens the attacker's profile under Users.
