Summary
The Jupiter X Core plugin for WordPress up to and including 4.62.0 does not sanitize or escape custom user meta fields submitted through Raven Register, a stored cross-site scripting flaw (CWE-79). An unauthenticated attacker can register an account and store script in these fields. The script runs when a user opens a page or post authored by that account that includes the Raven Author Box widget, which requires an administrator to assign authorship to the attacker's account.

Description from the CNA
The Jupiter X Core plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'fields[<custom_meta_field_id>]' parameter in all versions up to, and including, 4.62.0 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 an injected page. Execution requires that the attacker-registered account be assigned as the post_author of a page or post whose template includes the Raven Author Box widget, a fixture an administrator can create by reassigning authorship to any user including newly registered Subscribers.
