Name of the Vulnerable Software and Affected Versions Oxygen Builder plugin for WordPress versions up to, and including, 4.8

Description The issue is related to Stored Cross-Site Scripting via a custom field due to insufficient input sanitization and output escaping. This allows 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.

Recommendations For Oxygen Builder plugin for WordPress versions up to, and including, 4.8, update to version 4.8.1, which implements an optional filter to provide output escaping for dynamic data. As a temporary workaround, consider restricting access to custom fields to minimize the risk of exploitation.
