What the vulnerability does
01Description
The Profile Builder plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the plugin's user_meta and compare shortcodes in all versions up to, and including, 3.13.8 due to insufficient input sanitization and output escaping on user supplied attributes. This makes it possible for authenticated attackers, with contributor-level access and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page.
Explanation of Vulnerability in Simple Terms
02Summary

The vulnerability has a changed scope, meaning the impact extends beyond the vulnerable component itself. Site administrators should update to a version newer than 3.13.8 to remediate this issue.
